Subject: [PATCH] MFC r269106: Add a 'raw' parameter to the 'modinfo'
 subcommand.  This is handy when trying to figure out why a QSFP+/SFP+
 connector or cable wasn't identified correctly by cxgbe(4).  Its output looks
 like this:

# cxgbetool t5nex0 modinfo 0 raw
00:  03 04 21 00  00 00 00 00  ..!. ....
