[PATCH net-next 01/12] net: hns3: reuse the definition of l3 and l4 header info union

[Huazhong Tan]

From: liyongxin <liyongx...@huawei.com>

Union l3_hdr_info and l4_hdr_info have already been defined in
the hns3_enet.h, so it is unnecessary to define them elsewhere.

This patch removes the redundant definition, and reuses the one
defined in the hns3_enet.h.
