Hi!

Recent -current changes produce many

  wm0: wm_tx_offload: packet headers did not fit in first mbuf, packet dropped
  wm1: wm_tx_offload: packet headers did not fit in first mbuf, packet dropped

messages on one of our i386 machines (the only machine with wm* nics,
dmesg excerpt):

  wm0 at pci2 dev 10 function 0: Intel i82545EM 1000BASE-T Ethernet, rev. 1
  wm0: interrupting at ioapic0 pin 22 (irq 5)

Though the machines is still accessible from one side (for login e.
g.), it no longer routes network packets ...

A kernel compiled from Nov 13th -current sources does not show this
misbehavior.

Is this a known wm* issue? Did I miss some config changes?
