Xi Wang 1819e40908 net: hns3: Fix for VF mailbox cannot receiving PF response ... When the VF frequently switches the CMDQ interrupt, if the CMDQ_SRC is not cleared, the VF will not receive the new PF response after the interrupt is re-enabled, the corresponding log is as follows: [ 317.482222] hns3 0000:00:03.0: VF could not get mbx resp(=0) from PF in 500 tries [ 317.483137] hns3 0000:00:03.0: VF request to get tqp info from PF failed -5 This patch fixes this problem by clearing CMDQ_SRC before enabling interrupt and syncing pending IRQ handlers after disabling interrupt.
