I backed off from trying to just eliminate this variable, since
transforming atomic_inc_return() into atomic_inc() takes away
the memory barriers.Signed-off-by: David S. Miller

I was investigating some warnings that spew because of the
_DEBUG_FOO ifdef'ery in here.Instead of adding more ifdefs to fix that warning, let's use
pr_debug() and get rid of these CPP checks altogether.Signed-off-by: David S. Miller

Commit 4d95847381228639844c7197deb8b2211274ef22, entitled
"tg3: Workaround rx_discards stat bug", was intended to be applied to
the 5717, 5718, 5719_A0, and 5720 A0 chip revisions. The implementation
missed the latter two when applying the fix in a critical area. This
patch fixes the problem.Signed-off-by: Matt Carlson

This patch moves the code that asserts the TSO_CAPABLE flag closer to
where the TSO capabilities flags are set. There isn't a good enough

Commit 4d95847381228639844c7197deb8b2211274ef22, entitled
"tg3: Workaround rx_discards stat bug" modified the hardware statistics
data structure. The modification shifted the statistics so that the
labels no longer corresponded to the counter values. This patch fixes
the problem by utilizing reserved space for the new counters.Signed-off-by: Matt Carlson

Commit 21a00ab270f95d32e502d92f166dd75c518d3c5f, entitled
"tg3: Fix EEE interoperability issue", added an EEE interoperability
fix. We found that the fix doesn't work if applied too early though.
This patch delays the fix until right before allowing LPI assertion.Signed-off-by: Matt Carlson

Commit 4d163b75e979833979cc401ae433cb1d7743d57e, entitled
"tg3: Fix 5719 A0 tx completion bug" turned off TSO to fix a hardware
bug. In doing so, it accidentally turned off all IPv6 TCP checksum
offloading too. This patch fixes the problem by reenabling the hardware
bit that control both features. The TSO capability is still not exposed
to the kernel.Signed-off-by: Matt Carlson

This patch consolidates the skb cleanup code into a function named
tg3_skb_error_unmap(). The modification addresses a long-standing bug

pci_unmap_page() in tigon3_dma_hwbug_workaround().Signed-off-by: Matt Carlson

It has been recently discovered that all tg3 devices have a 4Gb boundary
DMA problem, and that all 5755 and newer devices can't handle fragments
less than or equal to 8 bytes in size. This patch adjusts the flags and
removes tg3_start_xmit(). tg3_start_xmit_dma_bug() has been renamed to
tg3_start_xmit().Signed-off-by: Matt Carlson

v3 -> v4: fix return boolean false instead of 0 for ic_is_init_dev
Currently the ip auto configuration has a hardcoded delay of 1 second.
When (ethernet) link takes longer to come up (e.g. more than 3 seconds),
nfs root may not be found.Remove the hardcoded delay, and wait for carrier on at least one network
device.Signed-off-by: Micha Nelissen

During the sctp_close() call, we do not use rcu primitives to
destroy the address list attached to the endpoint. At the same
time, we do the removal of addresses from this list before
attempting to remove the socket from the port hashAs a result, it is possible for another process to find the socket
in the port hash that is in the process of being closed. It then
proceeds to traverse the address list to find the conflict, only
to have that address list suddenly disappear without rcu() critical
section.Fix issue by closing address list removal inside RCU critical
section.Race can result in a kernel crash with general protection fault or
kernel NULL pointer dereference:kernel: general protection fault: 0000 [#1] SMP

ipv6 has per device ICMP SNMP counters, taking too much space because
they use percpu storage.needed size per device is :
(512+4)*sizeof(long)*number_of_possible_cpus*2On a 32bit kernel, 16 possible cpus, this wastes more than 64kbytes of
memory per ipv6 enabled network device, taken in vmalloc pool.Since ICMP messages are rare, just use shared counters (atomic_long_t)
Per network space ICMP counters are still using percpu memory, we might
also convert them to shared counters in a future patch.Signed-off-by: Eric Dumazet

It's way past it's usefulness. And this gets rid of a bunch
of stray ->rt_{dst,src} references.Even the comment documenting the macro was inaccurate (stated
default was 1 when it's 0).If reintroduced, it should be done properly, with dynamic debug
