This follows David Miller advice and tries to fix coalesce timer in
multi-queue scenarios.
We are now using per-queue coalesce values and per-queue TX timer.

Currently we are always setting the tail address of descriptor list to

According to databook this is not correct. Tail address should point to

In some situations some netlink attributes may be used for output

then helpful to be able to prevent userspace from using them in

From: Johannes Berg
Commonly, ethernet addresses are just using a policy of
{ .len = ETH_ALEN }
which leaves userspace free to send more data than it should,
which may hide bugs.
Introduce NLA_EXACT_LEN which checks for exact size, rejecting
the attribute if it's not exactly that length.

commit 40413955ee26 ("Cipso: cipso_v4_optptr enter infinite loop") fixed

assumes that ip_options_compile filtered out all zero length options and
that no other one-byte options beside IPOPT_END and IPOPT_NOOP exist.
