This makes the b43 driver just automatically fall back to PIO mode when
DMA doesn't work.
The driver already told the user to do it, so rather than have the user
reload the module with a new flag, just make the driver do it
automatically. We keep the message as an indication that something is
wrong, but now just automatically fall back to the hopefully working PIO
case.

If authentication has already been performed when the WLAN interface is
stopped, (sometimes) the ieee80211_work_purge would corrupt some
ieee80211_work-structures. The outcome is this (cleaned up):
[ 2252.398681] WARNING: at net/mac80211/work.c:995 ieee80211_work_purge
[ 2252.466430] Backtrace:

[ 2252.546875] (ieee80211_stop+0x0/0x4c0 [mac80211])
Additionally, one would get this, going on regarless of the WLAN interface
state, going on forever:

In "wireless: remove WLAN_80211 and WLAN_PRE80211 from Kconfig" I
inadvertantly missed a line in include/linux/netdevice.h. I thereby
effectively reverted "net: Set LL_MAX_HEADER properly for wireless." by
accident. :-( Now we should check there for CONFIG_WLAN instead.

Currently if a driver does not set hw.max_listen_interval a listen
interval of 1 is negotiated with the AP. Thus, the AP could drop
buffered frames for us after just one beacon interval which can
easily happen with the current powersave and scan implementation.
To avoid this issue increase the default interval to 5 which should
be a reasonable safe default.

While ath9k does not support RIFS yet, the ability to receive RIFS
frames is currently enabled for most chipsets in the initvals.
This is causing baseband related issues on AR9160 and AR9130 based
chipsets, which can lock up under certain conditions.
This patch fixes these issues by overriding the initvals, effectively
disabling RIFS for all affected chipsets.

The ISA skeleton net driver has been obsolete and unmaintained for many
years. Any hardware remotely like ISA will use the platform API and
look much more like a PCI driver, and make much better use of netdev
APIs such as NAPI.

Quick fix for memory/module refcount leak.
Reference count of listener instance never reaches 0.
Start/stop of ulogd2 is enough to trigger this bug!
Now, refcounting there looks very fishy in particular this code:
if (!try_module_get(THIS_MODULE)) {
...
and creation of listener instance with refcount 2,
so it may very well be ripped and redone. :-)

Clients will set their MTU to 1280 if they receive a
ICMPV6_PKT_TOOBIG message with an MTU less than 1280.
To allow encapsulating of packets over a 1280 link
we should always accept packets with a size of 1280
for forwarding even if the path has a lower MTU and
fragment the encapsulated packets afterwards.
In case a forwarded packet is not going to be encapsulated
a ICMPV6_PKT_TOOBIG msg will still be send by ip6_fragment()
with the correct MTU.

The drvinfo struct should include the number of strings that
get_rx_ntuple will return. It will be variable if an underlying
driver implements its own get_rx_ntuple routine, so userspace
needs to know how much data is coming.
