Subject: [PATCH 035/283] net: hns3: use capabilities queried from firmware
mainline inclusion
from mainline-v5.10-rc1
commit 4cc86cb58a9993a318a56aff1d7dacdf5252b2bc
category: feature
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EMQV
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4cc86cb58a9993a318a56aff1d7dacdf5252b2bc
--------------------------------
In order to improve code maintainability and compatibility, the
capabilities of new features are queried from firmware.
The member flag in struct hnae3_ae_dev indicates not only
capabilities, but some initialized status. As capabilities bits
queried from firmware is too many, it is better to use new member
to indicate them. So adds member capabs in struce hnae3_ae_dev.
