Add support to priority code point (PCP) that is an 3-bit field
which refers to IEEE 802.1p class of service and maps to the frame
priority level.
Values in order of priority are: 1 (Background (lowest)),
0 (Best effort (default)), 2 (Excellent effort),
3 (Critical applications), 4 (Video, < 100ms latency),
5 (Video, < 10ms latency), 6 (Internetwork control) and
7 (Network control (highest)).
Example of usage:
root# ifconfig em0.1 create
root# ifconfig em0.1 vlanpcp 3
Note:
The review D801 includes the pf(4) part, but as discussed with kristof,
we won't commit the pf(4) bits for now.
The credits of the original code is from rwatson.

Add support to priority code point (PCP) that is an 3-bit field
which refers to IEEE 802.1p class of service and maps to the frame
priority level.
Values in order of priority are: 1 (Background (lowest)),
0 (Best effort (default)), 2 (Excellent effort),
3 (Critical applications), 4 (Video, < 100ms latency),
5 (Video, < 10ms latency), 6 (Internetwork control) and
7 (Network control (highest)).
Example of usage:
root# ifconfig em0.1 create
root# ifconfig em0.1 vlanpcp 3
Note:
The review D801 includes the pf(4) part, but as discussed with kristof,
we won't commit the pf(4) bits for now.
The credits of the original code is from rwatson.
