The hostap_80211_rx() function is supposed to set up the mac addresses
for four possible cases, based on two bits of input data. For
some reason, gcc decides that it's possible that none of the these
four cases apply and the addresses remain uninitialized:
drivers/net/wireless/intersil/hostap/hostap_80211_rx.c: In function ‘hostap_80211_rx’:
arch/x86/include/asm/string_32.h:77:14: warning: ‘src’ may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/net/wireless/intel/ipw2x00/libipw_rx.c: In function ‘libipw_rx’:
arch/x86/include/asm/string_32.h:77:14: error: ‘dst’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
arch/x86/include/asm/string_32.h:78:22: error: ‘*((void *)&dst+4)’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This warning is clearly nonsense, but changing the last case into
'default' makes it obvious to the compiler too, which avoids the
warning and probably leads to better object code too.
The same code is duplicated several times in the kernel, so this
patch uses the same workaround for all copies. The exact configuration
was hit only very rarely in randconfig builds and I only saw it
in three drivers, but I assume that all of them are potentially
affected, and it's better to keep the code consistent.

This patch replaces uses of blkcipher with skcipher and the long
obsolete hash interface with ahash.

This indicates a driver key selection issue, but even then there's
no point in printing it all the time, so ratelimit it. Also remove
the priv pointer from it -- people debugging will only have a single
device anyway and it's useless as anything but a cookie.

Don't use create_proc_read_entry() as that is deprecated, but rather use
proc_create_data() and seq_file instead.

Standardize the net core ratelimited logging functions.
Coalesce formats, align arguments.
Change a printk then vprintk sequence to use printf extension %pV.

Removing unnecessary messages saves code and text.
Site specific OOM messages are duplications of a generic MM
out of memory message and aren't really useful, so just
delete them.

No change in output for pr_<level> prefixes.
netdev_<level> output is different, arguably improved.

Introduce TKIP_HDR_LEN define for code clarity (in the same way as
CCMP_HDR_LEN).
Also odd len variable (not used) dropped from lib80211_tkip_hdr().

When they were part of the now defunct ieee80211 component, these
messages were only visible when special debugging settings were enabled.
Let's mirror that with a new lib80211 debugging Kconfig option.

These bits are shared already between ipw2x00 and hostap, and could
probably be shared both more cleanly and with other drivers. This
commit simply relocates the code to lib80211 and adjusts the drivers
appropriately.
