      ixgbe: Match on multiple headers for cls_u32 offloads · 1cdaaf54
      由 Amritha Nambiar 提交于 
      Adds support to set filters with multiple header fields (L3,L4)to match on.
This is achieved in the following order:
1. Create a leaf hash table for the next header.
2. Create a link to the leaf hash table from the base hash table with
   matches on next header type and current header fields.
3. Add filter in leaf hash table with match on next header fields and
   action.

Verified with the following filters :

Match TCP and DIP:
        handle 1: u32 divisor 1
        u32 ht 800: order 1 link 1: \
        offset at 0 mask 0f00 shift 6 plus 0 eat \
        match ip protocol 6 ff match ip dst 10.0.0.1/32
        match tcp src 28 ffff action drop

Delete the filter:

Match on DIP, SIP, UDP (SPort, DPort):
        handle 2: u32 divisor 1
        u32 ht 800: order 2 link 2: \
        offset at 0 mask 0f00 shift 6 plus 0 eat \
        match ip dst 15.0.0.2/32 match ip protocol 17 ff \
        match ip src 15.0.0.1/32
        match udp src 30 ffff match udp dst 32 ffff action drop

      ixgbe: Add support for redirect action to cls_u32 offloads · 947f8a45
      由 Sridhar Samudrala 提交于 
      This patch enables 'redirect' to a SRIOV VF or a offloaded macvlan
device queue via tc 'mirred' action.

Verified with the following script that creates SRIOV VFs,  offloaded
macvlan and adds tc u32 filters with redirect action to the associated
netdevs.

 # add ingress qdisc.
 tc qdisc add dev p4p1 ingress

 # enable hw tc offload.
 ethtool -K p4p1 hw-tc-offload on

 # create 4 sriov VFs and bring up the first one.
 echo 4 > /sys/class/net/p4p1/device/sriov_numvfs
 sleep 1
 ip link set p4p1 up
 ip link set p4p1_0 up

 # create a offloaded macvlan device and bring it up.
 ethtool -K p4p1 l2-fwd-offload on
 ip link add link p4p1 name mvlan_1 type macvlan
 ip link set mvlan_1 up

 # add u32 filter with action to redirect to VF netdev
 tc filter add dev p4p1 parent ffff: protocol ip prio 99 \
    handle 800:0:1 u32 ht 800: \
    match ip src 192.168.1.3/32 \
    action mirred egress redirect dev p4p1_0

 # add u32 filter with action to redirect to macvlan netdev
 tc filter add dev p4p1 parent ffff: protocol ip prio 99 \
    handle 800:0:2 u32 ht 800: \
    match ip src 192.168.2.3/32 \
    action mirred egress redirect dev mvlan_1
