Subject: net: hns3: some changes of MSI-X bits in PPU(RCB)
Patch-mainline: v5.3-rc1
Git-commit: 9f65e5ef900f6590dc7c90ca2a956247da393b07
References: bsc#1104353 FATE#326415
This patch modifies print message of rx_q_search_miss from error to dfx to
prevent misleading users, because this interrupt may occur if we receive
packets during initialization of HNS3 driver.
Otherwise, this patch masks 28th bit of PPU_MPF_ABNORMAL_SRC2 which is now
meaningless.
