As I've reported, ath9k currently fails utterly when fragmentation
is enabled. This makes ath9k "support" hardware fragmentation by
not supporting fragmentation at all to avoid the double-free issue.
The patch also changes mac80211 to report errors from the driver
operation to userspace.
That hack in ath9k should be removed once the rate control algorithm
it has is fixed, and we can at that time consider removing the hw
fragmentation support entirely since it's not used by any driver.

ieee80211_bss_info_update() can return NULL. Verify that this is not the
case before calling ieee802111_rx_bss_put() which would trigger an oops

There's no checking that the HT IEs are of the right length
which can be used by an attacker to cause an out-of-bounds
access by sending a too short HT information/capability IE.
Fix it by simply pretending those IEs didn't exist when too
short.

When debugfs_create_dir fails, sta_info_debugfs_add_work will not
terminate because it will find the same station again and again.
This is possible whenever debugfs fails for whatever reason; one
reason is a race condition in mac80211, unfortunately we cannot
do much about it, so just document it, it just means some station
may be missing from debugfs.

This patch removes the module dependency between ctnetlink and
nf_nat by means of an indirect call that is initialized when
nf_nat is loaded. Now, nf_conntrack_netlink only requires
nf_conntrack and nfnetlink.
This patch puts nfnetlink_parse_nat_setup_hook into the
nf_conntrack_core to avoid dependencies between ctnetlink,
nf_conntrack_ipv4 and nf_conntrack_ipv6.
This patch also introduces the function ctnetlink_change_nat
that is only invoked from the creation path. Actually, the
nat handling cannot be invoked from the update path since
this is not allowed. By introducing this function, we remove
the useless nat handling in the update path and we avoid
deadlock-prone code.
This patch also adds the required EAGAIN logic for nfnetlink.

Nir Tzachar <nir.tzachar@gmail.com> reported a warning when sending
fragments over loopback with NAT:
[ 6658.338121] WARNING: at net/ipv4/netfilter/nf_nat_standalone.c:89 nf_nat_fn+0x33/0x155()
The reason is that defragmentation is skipped for already tracked connections.
This is wrong in combination with NAT and ip_conntrack actually had some ifdefs
to avoid this behaviour when NAT is compiled in.
The entire "optimization" may seem a bit silly, for now simply restoring the
lost #ifdef is the easiest solution until we can come up with something better.

PHYLIB has alread a depend on !S390, however select PHYLIB at DSA overrides
that unfortunately. So add a depend on !S390 to DSA as well.

older versions of gcc do not recognize that ieee80211_rx_h_mesh_fwding()
is unused when CONFIG_MAC80211_MESH is disabled:
net/built-in.o: In function `ieee80211_rx_h_mesh_fwding':
rx.c:(.text+0xd89af): undefined reference to `mpp_path_lookup'

as this code construct:
if (ieee80211_vif_is_mesh(&sdata->vif))
CALL_RXH(ieee80211_rx_h_mesh_fwding);
still causes ieee80211_rx_h_mesh_fwding() to be linked in.
Protect these places with an #ifdef.

Linus noted a build failure case:
net/netfilter/ipvs/ip_vs_xmit.c: In function 'ip_vs_tunnel_xmit':
net/netfilter/ipvs/ip_vs_xmit.c:616: error: implicit declaration of function 'ip_select_ident'
The proper include file (net/ip.h) is being included in ip_vs_xmit.c to get
that declaration. So the only possible case where this can happen is if
CONFIG_INET is not enabled.
This seems to be purely a missing dependency in the ipvs/Kconfig file IP_VS
entry.
Also, while we're here, remove the out of date "EXPERIMENTAL" string in the
IP_VS config help header line. IP_VS no longer depends upon CONFIG_EXPERIMENTAL
