Subject: ice: SW DCB, report correct max TC value
Patch-mainline: v5.7-rc1
Git-commit: 31c5f7f3f45aab8231c76be6d87c7503f442d019
References: jsc#SLE-12878
lldpad is using the value reported in the DCB config for
max_tc as the max allowed number of TCs, not the current
max. ICE driver was reporting it as current maximum TC.
Change DCB_NL function to report maximum TC allowed by
this device.
