[PATCH net-next 14/17] net: hns: modify tcam table of mac mc-entry

From: Salil Mehta
Date: Wed Nov 09 2016 - 13:16:00 EST


From: Qianqian Xie <xieqianqian@xxxxxxxxxx>

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