cxgbe/t4_tom: completely avoid L2T entries during stop/suspend.
1. Mark the L2T entry valid only if t4_write_l2e succeeds, which won't
happen if the adapter is stopped. This prevents L2T entries from
sometimes getting (re)promoted to VALID on Tx activity during stop.
2. Discard a work request immediately instead of enqueueing it to the
arp queue if the adapter is stopped.

imx clk: Skip reconfiguring the clock if we don't have a new best_parent
imx_clk_composite_find_best_parent can fail, when it does for all the
clocks checked we attempt to configure an uninitialized best_parent
leading to a panic.
Initialize best_parent and skip reconfiguring the clock if we don't find
a new best_parent to use.

pfctl: fix incorrect optimization
In the non-optimized case, an address list containing "any" (ie. { any 10.0.0.1 })
should be folded in the parser to any, not to 10.0.0.1. How long this bug has
been with us is unclear.

pf: allow filtering on the receive interface
add support to pf for filtering a packet by the interface it was received
on. use the received-on IFNAME filter option on a pf.conf rule to restrict
which packet the interface had to be received on. eg:
pass out on em0 from $foo to $bar received-on fxp0
ive been running this in production for a week now. i find it particularly
usefull with interface groups.
no objections, and a few "i like"s from henning, claudio, deraadt, mpf

amd64 la57_trampoline: turn off global pages and PCID before turning off paging
SDM is explicit that having CR4.PCID=1 while toggling CR3.PG causes #GP.
To be safe and to avoid some more effects, also turn off CR4.PGE.
