f061338015 be2net: support deleting FW dump via ethtool (only for Lancer)
This patch adds support to delete an existing FW-dump in Lancer via ethtool.
Initiating a new dump is not allowed if a FW dump is already present in the
adapter. The existing dump has to be first explicitly deleted.

d3d183126d be2net: ignore get/set profile FW cmd failures
Old versions of BE3 FW may not support cmds to re-provision (and hence
optimize) resources/queues in SR-IOV config. Do not treat this FW cmd
failure as fatal and fail the function initialization. Instead, just
enable SR-IOV with the resources provided by the FW.

Prior to the "create optimal number of queues on SR-IOV config" patch
such failures were ignored.

7ae457c1e5 net: filter: split 'struct sk_filter' into socket and bpf parts
clean up names related to socket filtering and bpf in the following way:
- everything that deals with sockets keeps 'sk_*' prefix
- everything that is pure BPF is changed to 'bpf_*' prefix

split 'struct sk_filter' into
struct sk_filter {
	atomic_t        refcnt;
	struct rcu_head rcu;
	struct bpf_prog *prog;
};
and
struct bpf_prog {
        u32                     jited:1,
                                len:31;
        struct sock_fprog_kern  *orig_prog;
        unsigned int            (*bpf_func)(const struct sk_buff *skb,
                                            const struct bpf_insn *filter);
        union {
                struct sock_filter      insns[0];
                struct bpf_insn         insnsi[0];
                struct work_struct      work;
        };
};
so that 'struct bpf_prog' can be used independent of sockets and cleans up
'unattached' bpf use cases

split SK_RUN_FILTER macro into:
    SK_RUN_FILTER to be used with 'struct sk_filter *' and
    BPF_PROG_RUN to be used with 'struct bpf_prog *'

__sk_filter_release(struct sk_filter *) gains
__bpf_prog_release(struct bpf_prog *) helper function

also perform related renames for the functions that work
with 'struct bpf_prog *', since they're on the same lines:

sk_filter_size -> bpf_prog_size
sk_filter_select_runtime -> bpf_prog_select_runtime
sk_filter_free -> bpf_prog_free
sk_unattached_filter_create -> bpf_prog_create
sk_unattached_filter_destroy -> bpf_prog_destroy
sk_store_orig_filter -> bpf_prog_store_orig_filter
sk_release_orig_filter -> bpf_release_orig_filter
__sk_migrate_filter -> bpf_migrate_filter
__sk_prepare_filter -> bpf_prepare_filter

API for attaching classic BPF to a socket stays the same:
sk_attach_filter(prog, struct sock *)/sk_detach_filter(struct sock *)
and SK_RUN_FILTER(struct sk_filter *, ctx) to execute a program
which is used by sockets, tun, af_packet

API for 'unattached' BPF programs becomes:
bpf_prog_create(struct bpf_prog **)/bpf_prog_destroy(struct bpf_prog *)
and BPF_PROG_RUN(struct bpf_prog *, ctx) to execute a program
which is used by isdn, ppp, team, seccomp, ptp, xt_bpf, cls_bpf, test_bpf

a5b5dc3ce4 xen-netfront: release per-queue Tx and Rx resource when disconnecting
Since netfront may reconnect to a backend with a different number of
queues, all per-queue Rx and Tx resources (skbs and grant references)
should be freed when disconnecting.

Without this fix, the Tx and Rx grant refs are not released and
netfront will exhaust them after only a few reconnections.  netfront
will fail to connect when no free grant references are available.

Since all Rx bufs are freed and reallocated instead of reused this
will add some additional delay to the reconnection but this is
expected to be small compared to the time taken by any backend hotplug
scripts etc.

3b57de958e net: stmmac: Support devicetree configs for mcast and ucast filter entries
This patch adds and modifies code to support multiple Multicast and Unicast
Synopsys MAC filter configurations. The default configuration is defined to
support legacy driver behavior, which is 64 Multicast bins. The Unicast
filter code previously assumed all controllers support 32 or 16 Unicast
addresses based on controller version number, but this has been corrected
to support a default of 1 Unicast address. The filter configuration may
be specified through the devicetree using a Synopsys specific device tree
entry. This information was verified with Synopsys through
Synopsys Support Case  and shared with the maintainer.

aefef4c15a net: stmmac: Correct set_filter for multicast and unicast cases
This patch removes the check for the number of mulitcast addresses
when using hash based filtering since it's not necessary. If the number
of multicast addresses in the list exceeds the number of multicast hash
bins, the bins will "fold" over into one of the bins configured and
enabled for the particular component instance.

The default number of maximum unicast addresses was changed from 32 to 1
since this number is not dependent on the component revision. The maximum
number of multicast and unicast addresses is dependent on the configuration
of the Synopsys EMAC configured by the SOC architect at the time the
features were selected and configured for a particular component. Sadly,
Synopsys does not provide a way to query the precise number supported
by a particular component, so we must fall back on a devicetree entry.
This configuration could vary from vendor to vendor (such as STMicro,
Altera, etc).

The multicast bins are set for every possible filtering case (including
no entries) - previously the bits were set only if multicast filter entries
were present.

bins and perfect filter entries at device creation time and there's no way

correctly for a particular device instance. This patch modifies the

can be set at initialization time.

Commit 34c5bd66e5ed introduced the possibility that an
uninitialized pointer on the stack (orig_fp) can call into
sk_unattached_filter_destroy() when its value is non NULL.

Before that commit orig_fp was only destroyed in the same
block where it was assigned a valid BPF prog before. Fix it
up by initializing it to NULL.

0c1d77dfb5 net: libphy: Add phy specific function to access mmd phy registers
libphy was originally written assuming all phy devices support clause 45
access extensions to the mmd registers through the indirection registers
located within the first 16 phy registers. This assumption is not true
in all cases, and one specific example is the Micrel ksz9021 10/100/1000
Mbps phy. Using the stmmac driver, accessing the mmd registers to query
and configure energy efficient Ethernet (EEE) features yielded unexpected
behavior.

This patch adds mmd access functions to the phy driver that can be
overriden by the phy specific driver if the phy does not support this
mechanism or uses it's own non-standard access mechanism. By default,
the IEEE Compatible clause 45 access mechanism described in clause 22
is used. With this patch, EEE query/configure functions as expected
using the stmmac and the Micrel ksz9021 phy.

34c5bd66e5 net: filter: don't release unattached filter through call_rcu()
sk_unattached_filter_destroy() does not always need to release the
filter object via rcu. Since this filter is never attached to the
socket, the caller should be responsible for releasing the filter
in a safe way, which may not necessarily imply rcu.

This is a short summary of clients of this function:

1) xt_bpf.c and cls_bpf.c use the bpf matchers from rules, these rules
   are removed from the packet path before the filter is released. Thus,
   the framework makes sure the filter is safely removed.

2) In the ppp driver, the ppp_lock ensures serialization between the
   xmit and filter attachment/detachment path. This doesn't use rcu
   so deferred release via rcu makes no sense.

3) In the isdn/ppp driver, it is called from isdn_ppp_release()
   the isdn_ppp_ioctl(). This driver uses mutex and spinlocks, no rcu.
   Thus, deferred rcu makes no sense to me either, the deferred releases
   may be just masking the effects of wrong locking strategy, which
   should be fixed in the driver itself.

4) In the team driver, this is the only place where the rcu
   synchronization with unattached filter is used. Therefore, this
   patch introduces synchronize_rcu() which is called from the
   genetlink path to make sure the filter doesn't go away while packets
   are still walking over it. I think we can revisit this once struct
   bpf_prog (that only wraps specific bpf code bits) is in place, then
   add some specific struct rcu_head in the scope of the team driver if
   Jiri thinks this is needed.

Deferred rcu release for unattached filters was originally introduced
in 302d663 ("filter: Allow to create sk-unattached filters").

5c10e5cb0f amd-xgbe-phy: Updates to KR training initiation
As part of changing rates to KR mode, KR training is initiated. If
the KR training is restarted it is possible to enter an invalid logic
state. This can be avoided by asserting a training reset bit before
initiating the KR training and then clearing the training reset bit.

2d871aa071 net: stmmac: add platform init/exit for Altera's ARM socfpga
This patch adds platform init/exit functions and modifications to support
suspend/resume for the Altera Cyclone 5 SOC Ethernet controller. The platform
exit function puts the controller into reset using the socfpga reset
controller driver. The platform init function sets up the Synopsys mac by
first making sure the Ethernet controller is held in reset, programming the
phy mode through external support logic, then deasserts reset through
the socfpga reset manager driver.

4d2f9bbb65 mlx5: Adjust events to use unsigned long param instead of void *
In the event flow, we currently pass only a port number in the
void *data argument.  Rather than pass a pointer to the event handlers,
we should use an "unsigned long" parameter, and pass the port number
value directly.

In the future, if necessary for some events, we can use the unsigned long
parameter to pass a pointer.

f241e7497e mlx5: minor fixes (mainly avoidance of hidden casts)
There were many places where parameters which should be u8/u16 were
integer type.

Additionally, in 2 places, a check for a non-null pointer was added
before dereferencing the pointer (this is actually a bug fix).

9603b61de1 mlx5: Move pci device handling from mlx5_ib to mlx5_core
In preparation for a new mlx5 device which is VPI (i.e., ports can be
either IB or ETH), move the pci device functionality from mlx5_ib
to mlx5_core.

This involves the following changes:
1. Move mlx5_core_dev struct out of mlx5_ib_dev. mlx5_core_dev
   is now an independent structure maintained by mlx5_core.
   mlx5_ib_dev now has a pointer to that struct.
   This requires changing a lot of places where the core_dev
   struct was accessed via mlx5_ib_dev (now, this needs to
   be a pointer dereference).
2. All PCI initializations are now done in mlx5_core. Thus,
   it is now mlx5_core which does pci_register_device (and not
   mlx5_ib, as was previously).
3. mlx5_ib now registers itself with mlx5_core as an "interface"
   driver. This is very similar to the mechanism employed for
   the mlx4 (ConnectX) driver. Once the HCA is initialized
   (by mlx5_core), it invokes the interface drivers to do
   their initializations.
4. There is a new event handler which the core registers:
   mlx5_core_event(). This event handler invokes the
   event handlers registered by the interfaces.

dabf24d168 bna: fill the magic in bnad_get_eeprom() instead of validating
A driver should fill magic field of ethtool_eeprom struct in .get_eeprom
and validate it in .set_eeprom. The bna incorrectly validates it in both
and this makes its .get_eeprom interface unusable.

2add511e58 net: mvpp2: fix 10 Mbit/s usage
This commit is similar to commit 4d12bc63ab5e ("net: mvneta: fix
operation in 10 Mbit/s mode"), but this time for the mvpp2 driver. The
driver was properly taking into account the 1 Gbit/s and 100 Mbit/s
speeds, but not the 10 Mbit/s, which was handled as 100
Mbit/s. However, the MVPP2_GMAC_CONFIG_MII_SPEED bit in the
MVPP2_GMAC_AUTONEG_CONFIG register must remain cleared to allow 10
Mbit/s operation. This commit therefore fixes 10 Mbit/s operation.
