Also update the mask first before calculating the vif index. Fixes an issue where adding back the same interfaces in a different order fails because of duplicate vif index use Fixes: 06662264ce2ad ("mt76x02: use mask for vifs") Signed-off-by: Felix Fietkau <nbd@nbd.name> --- drivers/net/wireless/mediatek/mt76/mt76x02_util.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-)
