RDMA/hns: Fix cmdq parameter of querying pf timer resource (441c88d5) · Commits · 戴 / test

The firmware has reduced the number of descriptions of command HNS_ROCE_OPC_QUERY_PF_TIMER_RES to 1. The driver needs to adapt, otherwise the hardware will report error 4(CMD_NEXT_ERR). Fixes: ("RDMA/hns: Add timer allocation support for hip08") Link: https://lore.kernel.org/r/1588931159-56875-3-git-send-email-liweihang@huawei.com Signed-off-by:
