Subject: RDMA/hns: Update some attributes of the RoCE device
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3a63c964eaa168c4ada1076b7c6ffd6a53a9ef86;p=openwrt%2Fstaging%2Fblogic.git

RDMA/hns: Update some attributes of the RoCE device

According to the IB protocol definition, the driver needs to show the
correct device information and the information will be queryed by device
attribute.
