VLANPrMap0
I/Opu VLAN priority mapping
This configuration chooses between 4 hard-wired mapping schemes
for the associations of VLAN priority within the received packet and
one of the 4 priority levels set by PriClass. The resolution function is
used for the final priority class if the receiving port already has a
priority level assigned by PriClass configuration, or the VLAN
prioritization is active.
VLANPrMap(0)is latched on reset.

'0' – flow control thresholds associated to each source port originating the
broadcast frames are considered FCBcstMode is latched on reset.
