cfg80211: clear SSID on disconnect/no connection
The SME state machine in cfg80211 uses the SSID stored

it in multiple places (when giving up on a connection

the SME state machine, but does matter for IBSS. Thus,
in those cases, clear the SSID to avoid messing up the

added a comment in the patch that explains the problem
better and also points to possible solutions -- which
I can't implement right now.

neigh: Convert garbage collection from softirq to workqueue
Current neigh_periodic_timer() function is fired by timer IRQ, and
scans one hash bucket each round (very litle work in fact)
As we are supposed to scan whole hash table in 15 seconds, this means
neigh_periodic_timer() can be fired very often. (depending on the number
of concurrent hash entries we stored in this table)
Converting this to a workqueue permits scanning whole table, minimizing
icache pollution, and firing this work every 15 seconds, independantly
of hash table size.
This 15 seconds delay is not a hard number, as work is a deferrable one.

IPVS: use pr_err and friends instead of IP_VS_ERR and friends
Since pr_err and friends are used instead of printk there is no point
in keeping IP_VS_ERR and friends. Furthermore make use of '__func__'
instead of hard coded function names.

The eeprom read & write commands currently check the E2P_CMD_LOADED_ bit is
set before allowing any operations. This prevents any reading or writing
unless a correctly programmed EEPROM is installed.
This patch removes the check, so it is possible to program blank EEPROMS
via ethtool.

This renames away a variable clash:
* ipv6_table[] is declared as a static global table;
* ipv6_sysctl_net_init() uses ipv6_table to refer/destroy dynamic memory;
* ipv6_sysctl_net_exit() also uses ipv6_table for the same purpose;
* both the two last functions call kfree() on ipv6_table.
