When a VM is providing an iSCSI target and the LUN is used by the
backend domain, the generated skbs for direct I/O writes to the disk
have large, multi-page skb->data but no frags.
With some lengths and starting offsets, xen_netbk_count_skb_slots()
would be one short because the simple calculation of
DIV_ROUND_UP(skb_headlen(), PAGE_SIZE) was not accounting for the
decisions made by start_new_rx_buffer() which does not guarantee
responses are fully packed.
For example, a skb with length < 2 pages but which spans 3 pages would
be counted as requiring 2 slots but would actually use 3 slots.
skb->data:
| 1111|222222222222|3333 |
Fully packed, this would need 2 slots:
|111122222222|22223333 |
But because the 2nd page wholy fits into a slot it is not split across
slots and goes into a slot of its own:
|1111 |222222222222|3333 |
Miscounting the number of slots means netback may push more responses
than the number of available requests. This will cause the frontend
to get very confused and report "Too many frags/slots". The frontend
never recovers and will eventually BUG.
Fix this by counting the number of required slots more carefully. In
xen_netbk_count_skb_slots(), more closely follow the algorithm used by
xen_netbk_gop_skb() by introducing xen_netbk_count_frag_slots() which
is the dry-run equivalent of netbk_gop_frag_copy().

Many of these devices support multiple QMI/wwan ports, requiring
multiple interface matching entries. All devices are composite,
providing a mix of one or more serial, storage or Android Debug

V5: remove sysfs support from this set, will rearchitect
changes from community comments
V4: addresses remaining community comments, mostly trivial edits.
major sparse based cleanup of possible endian issues
removal of most of __func__ references
sizeof(*var) instead of sizeof(struct ...)
change 'NULL ==' tests to !NULL

use kernel bitshift macros (upper_32_bits, etc)
V3: many more individual comments addressed, thanks reviewers! Many
other changes due to internal review and development.
V2: each patch has individual comments, in general, feedback from the
list was applied and addressed. Many changes due to internal review
and coding as well.
V1: initial send
Let me start by saying thanks and we appreciate any time spent by
those of you who review and comment on this new driver, and we will
attempt to address and respond to all issues brought to our attention.
I tried to break the patches up to ease review, but the series should
apply and still be bisectable, as the last patch adds the driver to
the kernel compile with CONFIG_I40E.
This driver is for a brand new bit of silicon that has a different
design than other Intel Ethernet silicon, and therefore needed a new
driver.
The hardware has quite a bit of capability and this driver is only
meant to provide basic functionality at first. Future patches will
continue to add functionality and bug fixes.
This initial release is very early in the product cycle with the intent
of getting initial support into the kernel before users have the
hardware available to purchase. A software development manual is not
ready yet but will be available when the hardware ships.
The driver development model and interaction with community submitted
patches *will not be any different* than what we are currently doing
today. We plan to continue established processes.
An associated i40evf driver has been posted for review.
List of tools we ran in preparation:
way more sparse clean
make W=1, W=2 clean
checkpatch (almost) clean
total: 1 errors, 4 warnings, 30461 lines checked
NOTE: Ignored message types: LONG_LINE
- issues have been addressed and the remainders
are noise.

During initialization bnx2x allocates significant amounts of memory
(for rx data, rx SGEs, TPA pool) using atomic allocations.
I received a report where bnx2x failed to allocate SGEs and it had
to fall back to TPA-less operation.
Let's use GFP_KERNEL allocations during initialization, which runs
in process context. Add gfp_t parameters to functions that are used
both in initialization and in the receive path.
Use an unlikely branch in bnx2x_frag_alloc() to avoid atomic allocation
by netdev_alloc_frag(). The branch is taken several thousands of times
during initialization, but then never more. Note that fp->rx_frag_size
is never greater than PAGE_SIZE, so __get_free_page() can be used here.

The kernel configuration for the driver could result in

are show below:
"on x86_64:

CONFIG_MMC=m
CONFIG_BRCMUTIL=y
CONFIG_BRCMFMAC=y
CONFIG_BRCMFMAC_SDIO=y
This bool kconfig symbol:
config BRCMFMAC_SDIO
bool "SDIO bus interface support for FullMAC driver"
depends on MMC
allows BRCMFMAC_SDIO to be y even when MMC=m.
Is there a reasonable solution to this?
This causes many build errors:

The cw1200_spi driver tries to mirror the cw1200_sdio driver's lock
API, which relies on sdio_claim_host/sdio_release_host to serialize
hardware operations across multiple threads.
Unfortunately the implementation was flawed, as it lacked a way to wake
up the lock requestor when there was contention, often resulting in a
hang.
This problem was uncovered while trying to fix the
spi-transfers-in-interrupt-context BUG() corrected in the previous
patch. Many thanks to Dave Sizeburns for his assistance in fixing this.

When we get an interrupt from the hardware, the first thing the driver does
is tell the device to mask off the interrupt line. Unfortunately this
involves a SPI transaction in interrupt context. Some (most?) SPI
controllers perform the transfer asynchronously and try to sleep.
This is bad, and triggers a BUG().
So, work around this by using adding a hwbus hook for the cw1200 driver
core to call. The cw1200_spi driver translates this into
irq_disable()/irq_enable() calls instead, which can safely be called in
interrupt context.
Apparently the platforms I used to develop the cw1200_spi driver used
synchronous spi_sync() implementations, which is why this didn't surface
until now.
Many thanks to Dave Sizeburns for the inital bug report and his services
as a tester.

Commit c0a77ec74f295013d7ba3204dd3ed25fccf83cb4 'bnx2x: Add missing braces in
bnx2x:bnx2x_link_initialize' identified indentation problem, but resolved it
by adding braces instead of fixing the indentation. The braces now prevents a
config_init call in some cases, though it should be called regardless of that
condition. This patch removes the braces and fix the confusing indentation
that caused this mess.

Merge commit 06c54055bebf did a bad conflict resolution accidentally
leaving out a closing brace. Add it back.
This breaks a handful of defconfigs on ARM, so it'd be good to see it
applied pretty quickly.

Pull networking changes from David Miller:
"Noteworthy changes this time around:
1) Multicast rejoin support for team driver, from Jiri Pirko.
2) Centralize and simplify TCP RTT measurement handling in order to
reduce the impact of bad RTO seeding from SYN/ACKs. Also, when
both timestamps and local RTT measurements are available prefer
the later because there are broken middleware devices which
scramble the timestamp.
From Yuchung Cheng.
3) Add TCP_NOTSENT_LOWAT socket option to limit the amount of kernel
memory consumed to queue up unsend user data. From Eric Dumazet.
4) Add a "physical port ID" abstraction for network devices, from
Jiri Pirko.
5) Add a "suppress" operation to influence fib_rules lookups, from
Stefan Tomanek.
6) Add a networking development FAQ, from Paul Gortmaker.
7) Extend the information provided by tcp_probe and add ipv6 support,
from Daniel Borkmann.
8) Use RCU locking more extensively in openvswitch data paths, from
Pravin B Shelar.
9) Add SCTP support to openvswitch, from Joe Stringer.
10) Add EF10 chip support to SFC driver, from Ben Hutchings.
11) Add new SYNPROXY netfilter target, from Patrick McHardy.
12) Compute a rate approximation for sending in TCP sockets, and use
this to more intelligently coalesce TSO frames. Furthermore, add
a new packet scheduler which takes advantage of this estimate when
available. From Eric Dumazet.
13) Allow AF_PACKET fanouts with random selection, from Daniel
Borkmann.
14) Add ipv6 support to vxlan driver, from Cong Wang"

Conflicts:
drivers/net/ethernet/stmicro/stmmac/stmmac_platform.c
net/bridge/br_multicast.c
net/ipv6/sit.c
The conflicts were minor:
1) sit.c changes overlap with change to ip_tunnel_xmit() signature.
2) br_multicast.c had an overlap between computing max_delay using
msecs_to_jiffies and turning MLDV2_MRC() into an inline function
with a name using lowercase instead of uppercase letters.
3) stmmac had two overlapping changes, one which conditionally allocated
and hooked up a dma_cfg based upon the presence of the pbl OF property,
and another one handling store-and-forward DMA made. The latter of
which should not go into the new of_find_property() basic block.

The indentation here implies that the intent was for this to be a multiline if.
