Subject: [PATCH 27/30] net/hns3: fix reset level comparison
|
|
|
|
[ upstream commit 1ceb5ad2dfdcc3e6658119d25253bced5be3cc32 ]
|
|
|
|
Currently, there are two problems in hns3vf_is_reset_pending():
|
|
1. The new detect reset level is not HNS3_NONE_RESET, but the
|
|
last reset level is HNS3_NONE_RESET, this function returns false.
|
|
2. Comparison between last_req and new_req is opposite.
|
|
|
|
In addition, the reset level comparison in hns3_detect_reset_event()
|
|
is similar to the hns3vf_is_reset_pending(). So this patch fixes
|
|
above the problems and merges the logic of reset level comparison.
|
|
|
|
Fixes: 5be38fc6c0fc ("net/hns3: fix multiple reset detected log")
