There was a lockdep which led to commit
fad003b6c8 ("Bluetooth: Fix inconsistent lock state with RFCOMM")
Lockdep noticed that `sk->sk_lock.slock' was acquired without disabling
the softirq while the lock was also used in softirq context.
Unfortunately the solution back then was to disable interrupts before
acquiring the lock which however made lockdep happy.
It would have been enough to simply disable the softirq. Disabling
interrupts before acquiring a spinlock_t is not allowed on PREEMPT_RT
because these locks are converted to 'sleeping' spinlocks.
Use spin_lock_bh() in order to acquire the `sk_lock.slock'.

This occurred when sending a v4 skb over vxlan6 over ipsec, in which case
skb->protocol == htons(ETH_P_IPV6) while skb->sk->sk_family == AF_INET in
xfrm_local_error(). Then it will go to xfrm6_local_error() where it tries
to get ipv6 info from a ipv4 sk.
This issue was actually fixed by Commit 628e341f31 ("xfrm: make local
error reporting more robust"), but brought back by Commit 844d48746e
("xfrm: choose protocol family by skb protocol").
So to fix it, we should call xfrm6_local_error() only when skb->protocol
is htons(ETH_P_IPV6) and skb->sk->sk_family is AF_INET6.

It's an error if the value of the RX/TX tail descriptor does not match
what was written. The error condition is true regardless the duration
of the interference from ME. But the driver only performs the reset if
E1000_ICH_FWSM_PCIM2PCI_COUNT (2000) iterations of 50us delay have
transpired. The extra condition can lead to inconsistency between the
state of hardware as expected by the driver.
Fix this by dropping the check for number of delay iterations.
While at it, also make __ew32_prepare() static as it's not used
anywhere else.

The way Rx queue assignment based on mac address, Ethertype and VLAN
priority filtering operates in I225 doesn't allow us to properly support
NFC rules with multiple matches.
Consider the following example which assigns to queue 2 frames matching
the address MACADDR *and* Ethertype ETYPE.
$ ethtool -N eth0 flow-type ether dst <MACADDR> proto <ETYPE> queue 2
When such rule is applied, we have 2 unwanted behaviors:
1) Any frame matching MACADDR will be assigned to queue 2. It
doesn't matter the ETYPE value.
2) Any accepted frame that has Ethertype equals to ETYPE, no matter
the mac address, will be assigned to queue 2 as well.
In current code, multiple-match filters are accepted by the driver, even
though it doesn't support them properly. This patch adds a check for
multiple-match rules in igc_ethtool_is_nfc_rule_valid() so they are
rejected.
