ea5c460023 net: ena: Always register RX queue info
The RX queue info contains information about the RX queue which might
be relevant to the kernel.

To avoid configuring this queue for different scenarios, this patch
moves the RX queue configuration to ena_up()/ena_down() function and
makes it configured every interface state toggle.

b626fd9627 net: ena: Refactor napi functions
This patch focuses on changes to the XDP part of the napi
polling routine.

1. Update the `napi_comp` stat only when napi is actually
   complete.
2. Simplify the code by using a function pointer to the right
   napi routine (XDP vs non-XDP path)
3. Remove unnecessary local variables.
4. Adjust a debug print to show the processed XDP frame index
   rather than the pointer.

911a8c9601 net: ena: Use tx_ring instead of xdp_ring for XDP channel TX
When an XDP program is loaded the existing channels in the driver split
into two halves:
- The first half of the channels contain RX and TX rings, these queues
  are used for receiving traffic and sending packets originating from
  kernel.
- The second half of the channels contain only a TX ring. These queues
  are used for sending packets that were redirected using XDP_TX
  or XDP_REDIRECT.

Referring to the queues in the second half of the channels as "xdp_ring"
can be confusing and may give the impression that ENA has the capability
to generate an additional special queue.

This patch ensures that the xdp_ring field is exclusively used to
describe the XDP TX queue that a specific RX queue needs to utilize when
forwarding packets with XDP TX and XDP REDIRECT, preserving the
integrity of the xdp_ring field in ena_ring.

23ec974980 net: ena: Introduce total_tx_size field in ena_tx_buffer struct
To avoid de-referencing skb or xdp_frame when we poll for TX completion
(where they might not be in the cache), save the total TX packet size in
the ena_tx_buffer object representing the packet.

Also the 'print_once' field's type was changed from u32 to u8 to allow
adding the 'total_tx_size' without changing the total size of the
struct.

009b387659 net: ena: Put orthogonal fields in ena_tx_buffer in a union
The skb and xdpf pointers cannot be set together in the driver
(each TX descriptor can send either an SKB or an XDP frame), and so it
makes more sense to put them both in a union.

This decreases the overall size of the ena_tx_buffer struct which
improves cache locality.

XDP system has a very large footprint in the driver's overall code.
makes the whole driver's code much harder to read.

Moving XDP code to dedicated files.

This patch doesn't make any changes to the code itself and only
cut-pastes the code into ena_xdp.c and ena_xdp.h files so the change
is purely cosmetic.

05d92cb0e9 selftests/net: change shebang to bash to support "source"
The patch set [1] added a general lib.sh in net selftests, and converted
several test scripts to source the lib.sh.

unicast_extensions.sh (converted in [1]) and pmtu.sh (converted in [2])
have a /bin/sh shebang which may point to various shells in different
distributions, but "source" is only available in some of them. For
example, "source" is a built-it function in bash, but it cannot be
used in dash.

Refer to other scripts that were converted together, simply change the
shebang to bash to fix the following issues when the default /bin/sh
points to other shells.

not ok 51 selftests: net: unicast_extensions.sh # exit=1

v1 -> v2:
  - Fix pmtu.sh which has the same issue as unicast_extensions.sh,
    suggested by Hangbin
  - Change the style of the "source" line to be consistent with other
    tests, suggested by Hangbin

2ab1efad60 net/sched: cls_api: complement tcf_tfilter_dump_policy
In function `tc_dump_tfilter`, the attributes array is parsed via
tcf_tfilter_dump_policy which only describes TCA_DUMP_FLAGS. However,
the NLA TCA_CHAIN is also accessed with `nla_get_u32`.

The access to TCA_CHAIN is introduced in commit 5bc1701881e3 ("net:
sched: introduce multichain support for filters") and no nla_policy is
provided for parsing at that point. Later on, tcf_tfilter_dump_policy is
introduced in commit f8ab1807a9c9 ("net: sched: introduce terse dump
flag") while still ignoring the fact that TCA_CHAIN needs a check. This
patch does that by complementing the policy to allow the access
discussed here can be safe as other cases just choose rtm_tca_policy as
the parsing policy.

501869fecf net: ethtool: Fix symmetric-xor RSS RX flow hash check
Commit 13e59344fb9d ("net: ethtool: add support for symmetric-xor RSS hash")
adds a check to the ethtool set_rxnfc operation, which checks the RX
flow hash if the flag RXH_XFRM_SYM_XOR is set. This flag is introduced
with the same commit. It calls the ethtool get_rxfh operation to get the
RX flow hash data. If get_rxfh is not supported, then EOPNOTSUPP is
returned.

There are driver like tsnep, macb, asp2, genet, gianfar, mtk, ... which
support the ethtool operation set_rxnfc but not get_rxfh. This results
in EOPNOTSUPP returned by ethtool_set_rxnfc() without actually calling
the ethtool operation set_rxnfc. Thus, set_rxnfc got broken for all
these drivers.

Check RX flow hash in ethtool_set_rxnfc() only if driver supports RX
flow hash.

3ce4f9c3fb net/ps3_gelic_net: Add gelic_descr structures
In an effort to make the PS3 gelic driver easier to maintain, create two
new structures, struct gelic_hw_regs and struct gelic_chain_link, and
replace the corresponding members of struct gelic_descr with the new
structures.

The new struct gelic_hw_regs holds the register variables used by the
gelic hardware device.  The new struct gelic_chain_link holds variables
used to manage the driver's linked list of gelic descr structures.

Michael Chan says:

====================
bnxt_en: Add basic ntuple filter support

The current driver only supports ntuple filters added by aRFS.  This
patch series adds basic support for user defined TCP/UDP ntuple filters
added by the user using ethtool.  Many of the patches are refactoring
patches to make the existing code more general to support both aRFS
and user defined filters.  aRFS filters always have the Toeplitz hash
value from the NIC.  A Toepliz hash function is added in patch 5 to
get the same hash value for user defined filters.  The hash is used
to store all ntuple filters in the table and all filters must be
hashed identically using the same function and key.

v2: Fix compile error in patch #4 when CONFIG_BNXT_SRIOV is disabled.

c029bc30b9 bnxt_en: Add support for ntuple filters added from ethtool.
Add support for adding user defined ntuple TCP/UDP filters.  These
filters are similar to aRFS filters except that they don't get aged.
Source IP, destination IP, source port, or destination port can be
unspecifed as wildcard.  At least one of these tuples must be specifed.
If a tuple is specified, the full mask must be specified.

All ntuple related ethtool functions are now no longer compiled only
for CONFIG_RFS_ACCEL.

300c191800 bnxt_en: Add ntuple matching flags to the bnxt_ntuple_filter structure.
aRFS filters match all 5 tuples.  User defined ntuple filters may
specify some of the tuples as wildcards.  To support that, we add the
ntuple_flags to the bnxt_ntuple_filter struct to specify which tuple
fields are to be matched.  The matching tuple fields will then be
passed to the firmware in bnxt_hwrm_cfa_ntuple_filter_alloc() to create
the proper filter.

Change the unused flag to BNXT_FLTR_INSERTED.  To prepare for multiple
pathways that an ntuple filter can be deleted, we add this flag.  These
filter structures can be retreived from the RCU hash table but only
the caller that sees that the BNXT_FLTR_INSERTED flag is set can delete
the filter structure and clear the flag under spinlock.
