net: hns3: fix get wrong pfc_en when query PFC configuration
mainline inclusion from mainline-v5.14 commit 8c1671e0 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I46N6O CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8c1671e0d13d4a0ba4fb3a0da932bf3736d7ff73 ---------------------------------------------------------------------- Currently, when query PFC configuration by dcbtool, driver will return PFC enable status based on TC. As all priorities are mapped to TC0 by default, if TC0 is enabled, then all priorities mapped to TC0 will be shown as enabled status when query PFC setting, even though some priorities have never been set. for example: $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off $ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on To fix this problem, just returns user's PFC config parameter saved in driver.
