[ Upstream commit 82b5321460005ac5d34996e17f5a51a4004a1e14 ]
handle->reset_level is assigned to HNAE3_NONE_RESET when client is
initialized, if a tx timeout happens right after initialization,
then handle->reset_level is not resetted to HNAE3_FUNC_RESET in
hclge_reset_event, which will cause reset event not properly
handled problem.
This patch fixes it by setting handle->reset_level properly when
client is initialized.
Fixes: 6d4c3981a8d8 ("net: hns3: Changes to make enet watchdog timeout func common for PF/VF")
