Subject: net: hns3: fix for HNS3_RXD_GRO_SIZE_M macro
Patch-mainline: Queued in subsystem maintainer repository
Git-repo: git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next.git
Git-commit: eff858c178fcc513e620bb803b4e3bfb9727856c
References: bsc#1104353 FATE#326415 bsc#1137201
According to hardware user menual, the GRO_SIZE is 14 bits width,
the HNS3_RXD_GRO_SIZE_M is 10 bits width now, which may cause
hardware GRO received packet error problem.
