commit 3fa5a0f5b0d69e31c6476cd81afeca3cc25a4927 upstream.
When CONFIG_PM isn't defined we don't have the function
ieee80211_sta_restart() compiled in, but we always need
it now for firmware restart. Move it out of the ifdef.

[ Upstream commit d5953d680f7e96208c29ce4139a0e38de87a57fe ]
If access to offset + length is larger than the skbuff length, then
skb_checksum() triggers BUG_ON().
skb_checksum() internally subtracts the length parameter while iterating
over skbuff, BUG_ON(len) at the end of it checks that the expected
length to be included in the checksum calculation is fully consumed.

[ Upstream commit 04c20a9356f283da623903e81e7c6d5df7e4dc3c ]
As documented in skbuff.h, devices with NETIF_F_IPV6_CSUM capability
can only checksum TCP and UDP over IPv6 if the IP header does not
contains extension.
This is enforced for UDP packets emitted from user-space to an IPv6
address as they go through ip6_make_skb(), which calls
__ip6_append_data() where a check is done on the header size before
setting CHECKSUM_PARTIAL.
But the introduction of UDP encapsulation with fou6 added a code-path
where it is possible to get an skb with a partial UDP checksum and an
IPv6 header with extension:
* fou6 adds a UDP header with a partial checksum if the inner packet
does not contains a valid checksum.
* ip6_tunnel adds an IPv6 header with a destination option extension
header if encap_limit is non-zero (the default value is 4).
The thread linked below describes in more details how to reproduce the
problem with GRE-in-UDP tunnel.
Add a check on the network header size in skb_csum_hwoffload_help() to
make sure no IPv6 packet with extension header is handed to a network
device with NETIF_F_IPV6_CSUM capability.
