skb->vlan_present seems redundant.
We can instead derive it from this boolean expression:
vlan_present = skb->vlan_proto != 0 || skb->vlan_tci != 0
Add a new union, to access both fields in a single load/store
when possible.
union {
u32 vlan_all;
struct {
__be16 vlan_proto;
__u16 vlan_tci;
};
};
This allows following patch to remove a conditional test in GRO stack.
Note:
We move remcsum_offload to keep TC_AT_INGRESS_MASK
and SKB_MONO_DELIVERY_TIME_MASK unchanged.
