sys/dev/nfe if_nfe.c if_nfereg.h
Log:
Increase a maximum segment size of DMA to 4096. Previously it used
MCLBYTES for the segment size but it used too many Tx descriptors in
TSO case.
While I'm here adjust maximum size of the sum of all segment lengths
in a given DMA mapping to 65535, the maximum size, in bytes, of a IP
packet.
