      net: fix 64 bit counters on 32 bit arches · 28172739
      由 Eric Dumazet 提交于 
      There is a small possibility that a reader gets incorrect values on 32
bit arches. SNMP applications could catch incorrect counters when a
32bit high part is changed by another stats consumer/provider.

One way to solve this is to add a rtnl_link_stats64 param to all
ndo_get_stats64() methods, and also add such a parameter to
dev_get_stats().

Rule is that we are not allowed to use dev->stats64 as a temporary
storage for 64bit stats, but a caller provided area (usually on stack)

Old drivers (only providing get_stats() method) need no changes.

      ixgbe: fix automatic LRO/RSC settings for low latency · 28c8e479
      由 Andy Gospodarek 提交于 
      This patch added to 2.6.34:

	commit f8d1dcaf
	Author: Jesse Brandeburg <jesse.brandeburg@intel.com>
	Date:   Tue Apr 27 01:37:20 2010 +0000

	    ixgbe: enable extremely low latency

introduced a feature where LRO (called RSC on the hardware) was disabled
automatically when setting rx-usecs to 0 via ethtool.  Some might not
like the fact that LRO was disabled automatically, but I'm fine with
that.  What I don't like is that LRO/RSC is automatically enabled when
rx-usecs is set >0 via ethtool.

This would certainly be a problem if the device was used for forwarding
and it was determined that the low latency wasn't needed after the
device was already forwarding.  I played around with saving the state of
LRO in the driver, but it just didn't seem worthwhile and would require
a small change to dev_disable_lro() that I did not like.

This patch simply leaves LRO disabled when setting rx-usecs >0 and
requires that the user enable it again.  An extra informational message
will also now appear in the log so users can understand why LRO isn't
being enabled as they expect.

Inconsistency of LRO setting first noticed by Stanislaw Gruszka.

      drivers/net: Remove unnecessary returns from void function()s · a4b77097
      由 Joe Perches 提交于 
      This patch removes from drivers/net/ all the unnecessary
return; statements that precede the last closing brace of
void functions.

It does not remove the returns that are immediately
preceded by a label as gcc doesn't like that.

It also does not remove null void functions with return.

Done via:
$ grep -rP --include=*.[ch] -l "return;\n}" net/ | \
  xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }'

with some cleanups by hand.

Compile tested x86 allmodconfig only.
