Subject: [PATCH] net/hns3: fix double decrement of secondary count
|
|
|
|
The "secondary_cnt" indicates the number of secondary processes on an
|
|
Ethernet device. But the variable is double subtracted when detach the
|
|
device in secondary processes.
|
|
|
|
Fixes: ff6dc76e40b8 ("net/hns3: refactor multi-process initialization")
