From 5bffde62a18098a4268e56c5dea175e208fa0cf4 Mon Sep 17 00:00:00 2001 From: Yonglong Liu Date: Sat, 4 Jan 2020 10:49:26 +0800 Subject: [PATCH] net: hns3: modify the IRQ name of TQP vector When rename the net devices, the IRQ number can not be fetched by the net device name, because the driver request the IRQ resources only when the vector resource changed, and the rename operation did not change the vector resources, so the IRQ name keeps the previous net device name. So this patch modifies the name of the TQP IRQ as "pci driver name"-"pci name"-"TxRx"-"index". Signed-off-by: Yonglong Liu Signed-off-by: Huazhong Tan Signed-off-by: David S.
