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.

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.

This patch moves the code that asserts the TSO_CAPABLE flag closer to

"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.

Commit 4d163b75e979833979cc401ae433cb1d7743d57e, entitled
"tg3: Fix 5719 A0 tx completion bug" turned off TSO to fix a hardware

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

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

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 hash
As 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:

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*2
On 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.

We need to keep the TX queues stopped throughout a reset, without
triggering the TX watchdog and regardless of the link state. The
proper way to do this is to use netif_device_{detach,attach}() just as
we do around suspend/resume, rather than the current bodge of faking
link-down.
Since we also need to do this during an offline self-test and we
perform a reset during that, add these function calls outside of
efx_reset_down() and efx_reset_up().

Those reduced to DEBUG can possibly be triggered by unprivileged processes
and are nothing exceptional. Illegal checksum combinations can only be
caused by driver bug, so promote those messages to WARN.
Since GSO without SG will now only cause DEBUG message from

During initialization of vmxnet3, the state of LRO
gets out of sync with netdev->features.
This leads to very poor TCP performance in a IP forwarding
setup and is hitting many VMware users.
Simplified call sequence:
1. vmxnet3_declare_features() initializes "adapter->lro" to true.
2. The kernel automatically disables LRO if IP forwarding is enabled,
so vmxnet3_set_flags() gets called. This also updates netdev->features.
3. Now vmxnet3_setup_driver_shared() is called. "adapter->lro" is still
set to true and LRO gets enabled again, even though
netdev->features shows it's disabled.
Fix it by updating "adapter->lro", too.
The private vmxnet3 adapter flags are scheduled for removal
in net-next, see commit a0d2730c9571aeba793cb5d3009094ee1d8fda35
"net: vmxnet3: convert to hw_features".
Patch applies to 2.6.37 / 2.6.38 and 2.6.39-rc6.
