[PATCH net-next 10/17] net: hns: modify tcam table and set mac key

[Salil Mehta]

From: Qianqian Xie <xieqianqian@xxxxxxxxxx>

The current definition of dsaf_drv_tbl_tcam_key is only suitable for
Little-endian. If data is stored in Big-endian, this may lead to
error in data use. Shift operation can make it work normally in both
Big-endian and Little-endian.
