Subject: net/hns3: fix possible truncation of hash key when config
|
|
|
|
[ upstream commit bb38316e738ad6009b3f20b3abfaf27ea8cb0202 ]
|
|
|
|
The hash key length of hns3 driver is obtained from firmware. If the
|
|
length is a multiple of HNS3_RSS_HASH_KEY_NUM (16), the last part
|
|
of hash key will be truncated.
|
|
|
|
Fixes: 88347111eb53 ("net/hns3: refactor set RSS hash algorithm and key interface")
