Chelsio netmap support ? (RELENG_11)

[Mike Tancsa]

I have a Chelsio T520 NIC that I have been trying to get netmap working
with. I see reference to the ncxl# vs cxl# interface on the lists, but I
never see ncxl come up.  The man pages dont say anything about having to
specifically enable anything that I can see.  I am using RELENG11 as of
today (r314848).

netmap seems to activate on the onboard igb NICs.
