Prepare for the removal in FreeBSD 12.0 of nxge(4) which supported the defunct company S2IO/Neterion Xframe-I and Xframe-II Ethernet adapters.
My justification:
This company was part of the 2000s 10g boom but did not really make it past the turn of the decade. Mailing list and bugzilla activity are not indicative of (remaining?) users. The nxge(4) hardware is high power draw (XENPAK or XFP MAC and older DSP). The driver does not use standard ring buffer management code. It supports what is now the industry standard stateless offload feature set so there is no continuing didactic value to the code.
Relnotes: yes
