Hi
I'm trying to map the vlan_pcp onto 802.11 tid.
net/wireless/util.c in mac80211 specifies:
> /* skb->priority values from 256->263 are magic values to
> * directly indicate a specific 802.1d priority. This is used
> * to allow 802.1d priority to be passed directly in from VLAN
> * tags, etc.
> */
> if (skb->priority >= 256 && skb->priority <= 263)
> return skb->priority - 256;
However the function dpif_netlink_queue_to_priority in /lib/dpif-netlink.c sets:
> if (queue_id < 0xf000) {
> *priority = TC_H_MAKE(1 << 16, queue_id + 1);
With this the lowest skb_priority I can set is 0x10001, slightly over the magic
values I need to use ;)
Why is this offset of 0x10000 + 1 in place?
Is something else in ovs about which I'm not aware dependant on this offset?

Matthias
