[ Upstream commit 366c304741729e64d778c80555d9eb422cf5cc89 ]
LRO/GRO_HW should be disabled if there is an attached XDP program.
BNXT_FLAG_TPA is the current setting of the LRO/GRO_HW. Using
BNXT_FLAG_TPA to disable LRO/GRO_HW will cause these features to be
permanently disabled once they are disabled.
Fixes: 1dc4c557bfed ("bnxt: adding bnxt_xdp_build_skb to build skb from multibuffer xdp_buff")
