Subject[PATCH 2/5] staging/slicoss: Remove always true if statement
Date
skbtype is assigned once to NORMAL_ETHFRAME and then checked if it is
NORMAL_ETHFRAME -> remove the checks.

This also gets rid of the (false positive) smatch warning:
slicoss.c:2829 slic_xmit_start() error: potential NULL dereference
'hcmd'.
