I don't know, but
You could disable various offloading to see if one of them is flaky.
This is the usual suspect.
You could find if_wm.c and read the cvs history.
of course this could be about the stack in general and not wm and
perhpas your particular wm chip, but if so, I probably would have
heard about it and remember
from a wm0 I have:
capabilities=7ff80<TSO4,IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx>
capabilities=7ff80<TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx,TCP6CSUM_Rx>
capabilities=7ff80<TCP6CSUM_Tx,UDP6CSUM_Rx,UDP6CSUM_Tx,TSO6>
enabled=0
ec_capabilities=17<VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,EEE>
ec_enabled=3<VLAN_MTU,VLAN_HWTAGGING>
