ok by msaitoh@n.o.

(knakahara)

ixg(4) supports workqueue poll mode, but not enabled by default yet. (that is, the default behavior is *not* changed)

At the time of high load near the wire rate, the turnaround time
of update/delete processing such as "ifconfig ixg0 inet XXX" or
"ifconfig ixg0 delete" is very long. The main reason is CPU
starvation caused by ixg(4)'s softint poll mode. ixg(4) uses
workqueue poll mode instead of softint poll mode, so that this
problem will be fix.

This change may cause performance issues, so it is not enabled
by default yet. Although there are that issues, if you want to use
workqueue poll mode, do "sysctl -w hw.ixgXX.txrx_workqueue=1" while
there is no traffic on the ixgXX.

Fix poll mode assumption breaking.
ixgbe_{enable,disable}_intr() forcibly enable/disable all interrupts

that is, queue interrupts must not occur while polling Tx/Rx rings.
E.g. "ifconfig ixg0 delete && ifconfig ixg0 192.168.0.1" on heavy
load traffic can causes this issue.
This fix may have 1% or 2% performance impact at short packets.

ixgbe_rearm_queues() which is called only via watchdog can also break
this poll mode assumption because writing EICS casues interrupts
immediately when interrupt auto mask enabled.

Remove these two KASSERTs. Thinking about it, they may fire when the user
enters "sysctl -w machdep.svs.enabled=0", if the xcall is received between
the 'svs_enabled' check in the caller and the same check in these KASSERTs.

In such a case we perform an SVS operation with svs_enabled set to false,
but that's intentional: after it is done svs_pmap_sync and svs_lwp_switch
won't be called anymore, the pdir synchronization is dropped.

It was intended as an optimization, but it increases the attack surface:
the IPsec policy is not enforced on RST packets when the socket is in the

between two IPsec hosts by sending RST packets between the client's SYN
and ACK packets.
