SVN rev 190307 on 2009-03-23 03:03:44Z by scf
Merge r189866 from head to stable/7:
Add the SIOCSIFMTU ioctl handling directly to tap(4) permitting it to have
its MTU set higher than 1500 (ETHERMTU). Its new limit is now 65535 as
enforced by ifhwioctl() in if.c
This allows a tap(4) device to be added to a bridge, which requires all
interface members to have the same MTU, with an interface configured for
jumbo frames. QEMU may now connect to a network via tap(4) without
requiring the real interface to have its MTU set to 1500 or lower.

Merge r189907 from head to stable/7:
Remove the splimp()/splx() calls around the setting of the MTU. They are
no-op's that I inadvertently added. Even if locking is needed in general
for the ioctl's, setting a single long will not need it due to the
operation being atomic.
