When the kernel is requested to mount a filesystem with a bad superblock
check hash, it would set the flag in the superblock requesting that the
fsck(8) program be run. The flag is only written to disk as part of a
superblock update. Since the superblock always has its check hash updated
when it is written to disk, the problem for which the flag has been set
will no longer exist. Hence, it is counter-productive to set the flag
as it will just cause an unnecessary run of fsck if it ever gets written.

When TCP_MD5SIG is set on a socket, all packets are dropped that don't
contain an MD5 signature. Relax this behavior to accept a non-signed
packet when a security association doesn't exist with the peer.
This is useful when a listen socket set with TCP_MD5SIG wants to handle
connections protected with and without MD5 signatures.

We never initialized hw->conf.flags for IEEE80211_CONF_IDLE but
on set_channel we would clear it and announce a change.
This lead to a problem that drivers may do some work every time
which was not needed and may lead to unexpected behaviour (for no
better driver code).
Properly initialize conf.flags with IEEE80211_CONF_IDLE.
Factor out the toggling into a function and clear IDLE while
sw scanning and when associated and set again when scan ends
or we are bouncing out of assoc.
