msk(4) does not support VLAN hardware filter and LRO.  However I

There was a related change after 9.0-RELEASE. The change already
merged to stable/9(r229874)  So would you try latest stable/9 or
apply the change to 9.0-RELEASE?

If you've upgraded from somewhat old FreeBSD releases, make sure to
cold boot your box(i.e. completely remove power cord for several
