Subject[PATCH V3 for-next 07/11] IB/hns: Modify the macro for the timeout when cmd process
Date
From: "Wei Hu (Xavier)" <xavier.huwei@huawei.com>

This patch modified the macro for the timeout when cmd is
processing as follows:
Before modification:
enum {
HNS_ROCE_CMD_TIME_CLASS_A = 10000,
HNS_ROCE_CMD_TIME_CLASS_B = 10000,
HNS_ROCE_CMD_TIME_CLASS_C = 10000,
};
After modification:
#define HNS_ROCE_CMD_TIMEOUT_MSECS 10000
