Joe Perches a4b770972b drivers/net: Remove unnecessary returns from void function()s
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.

Eric Dumazet 1ae5dc342a net: trans_start cleanups
Now that core network takes care of trans_start updates, dont do it
in drivers themselves, if possible. Drivers can avoid one cache miss
(on dev->trans_start) in their start_xmit() handler.

Exceptions are NETIF_F_LLTX drivers

Jiri Pirko 22bedad3ce net: convert multicast list to list_head
Converts the list and the core manipulating with it to be the same as uc_list.

+uses two functions for adding/removing mc address (normal and "global"
 variant) instead of a function parameter.
+removes dev_mcast.c completely.
+exposes netdev_hw_addr_list_* macros along with __hw_addr_* functions for
 manipulation with lists on a sandbox (used in bonding and 80211 drivers)

Jiri Pirko 4cd24eaf0c net: use netdev_mc_count and netdev_mc_empty when appropriate
This patch replaces dev->mc_count in all drivers (hopefully I didn't miss
anything). Used spatch and did small tweaks and conding style changes when
it was suitable.

Daniel Drake 1f04493123 Fix MAC address access in 3c507, ibmlana, pcnet32 and libertas
Commit f001fde5ea changed
net_device.dev_addr from a 32-byte array to a pointer.

I found 4 ethernet drivers which rely on sizeof(dev_addr), which are now
only copying 4 bytes of the address information on 32bit systems.

Fix them to use ETH_ALEN.

Don Fry 63097b3ad8 pcnet32: VLB support fixes
VLB support has been broken since at least 2004-2005 period as some
changes introduced back then assumed that ->pci_dev is always valid,
lets try to fix it:

- remove duplicated SET_NETDEV_DEV() call

- call SET_NETDEV_DEV() only for PCI devices

- check for ->pci_dev validity in pcnet32_open()

[ Alternatively we may consider removing VLB support but there would not
  be much gain in it since an extra driver code needed for VLB support is
  minimal and quite simple. ]
