Subject: [PATCH net-next v2 0/4] Support MACsec VLAN
Dear maintainers,
This patch series introduces support for hardware (HW) offload MACsec
devices with VLAN configuration. The patches address both scenarios
where the VLAN header is both the inner and outer header for MACsec.
The changes include:
1. Adding MACsec offload operation for VLAN.
2. Considering VLAN when accessing MACsec net device.
3. Currently offloading MACsec when it's configured over VLAN with
current MACsec TX steering rules would wrongly insert the MACsec sec tag
after inserting the VLAN header. This resulted in an ETHERNET | SECTAG |
VLAN packet when ETHERNET | VLAN | SECTAG is configured. The patche
handles this issue when configuring steering rules.
4. Adding MACsec rx_handler change support in case of a marked skb and a
mismatch on the dst MAC address.
Please review these changes and let me know if you have any feedback or
concerns.
Updates since v1:
- Consult vlan_features when adding NETIF_F_HW_MACSEC.
- Allow grep for the functions.
- Add helper function to get the macsec operation to allow the compiler
to make some choice.
Thanks,
Emeel
