[PATCH net-next 11/17] net: hns: modify tcam table of mac uc-entry

From: Salil Mehta
Date: Wed Nov 09 2016 - 13:15:47 EST


From: Qianqian Xie <xieqianqian@xxxxxxxxxx>

The current definition of mac_uc_entry is only suitable for
Little-endian. Thus it needs to modify tcam table of mac uc-entry
to support both Little-endian and Big-endian.
