What do you mean the ksz8769 driver could only add one VLAN? That is obviously a false statement. All VLANs use the same FID of 1 means that the switch is currently configured for shared address learning. Whereas each VLAN having a separate FID would mean that it is configured for individual address learning. > This commit allows setting a FID for each new active VLAN. > The FID list is stored in a static table dynamically allocated from > ks8795_fid structure. > Each newly activated VLAN is associated to the next available FID. > Only the VLAN 0 is not added to the list as it is a special VLAN. > As it has a special meaning, see IEEE 802.1q. > When a VLAN is no more used, the associated FID table entry is reset > to 0. Why is this patch targeting the "net" tree? What is the problem that it resolves?
