m_mpls: add mac_push action
|
|
|
2f28bf |
|
|
|
2f28bf |
Add support for the new TCA_MPLS_ACT_MAC_PUSH action (kernel commit
|
|
|
2f28bf |
a45294af9e96 ("net/sched: act_mpls: Add action to push MPLS LSE before
|
|
|
2f28bf |
Ethernet header")). This action let TC push an MPLS header before the
|
|
|
2f28bf |
MAC header of a frame.
|
|
|
2f28bf |
|
|
|
2f28bf |
Example (encapsulate all outgoing frames with label 20, then add an
|
|
|
2f28bf |
outer Ethernet header):
|
|
|
2f28bf |
# tc filter add dev ethX matchall \
|
|
|
2f28bf |
action mpls mac_push label 20 ttl 64 \
|
|
|
2f28bf |
action vlan push_eth dst_mac 0a:00:00:00:00:02 \
|
|
|
2f28bf |
src_mac 0a:00:00:00:00:01
|
|
|
2f28bf |
|
|
|
2f28bf |
This patch also adds an alias for ETH_P_TEB, since it is useful when
|
|
|
2f28bf |
decapsulating MPLS packets that contain an Ethernet frame.
|
|
|
2f28bf |
|
|
|
2f28bf |
With MAC_PUSH, there's no previous Ethertype to modify. However, the
|
|
|
2f28bf |
"protocol" option is still needed, because the kernel uses it to set
|
|
|
2f28bf |
skb->protocol. So rename can_modify_ethtype() to can_set_ethtype().
|
|
|
2f28bf |
|
|
|
2f28bf |
Also add a test suite for m_mpls, which covers the new action and the
|
|
|
2f28bf |
pre-existing ones.
