KSZ9477 and KSZ8 switches has 4 queues per port whereas LAN937x has 8
queues. So Default TC MAP for LAN937x will be 0x76543210. Instead of
using this values for all the switch, this value must be derived based
on chip info. Can you consider to add this value in chip_info and use
it in funciton ksz_tc_ets_del based on the switch type, So that the
function will be generic.
