[V1,2/2] test_plans/cvl_limit_value_test: modify maximum value of switch rule
Commit Message
confirm with developer that CVL support up to 32K FLU entries. Firmware allocates
some default entries first, the actual entries can't be calculated and depend on
hardware. there is no formula to figure out the specific rule numbers of different
environment configurations,so can't acquire the actual number of free entries.
dts case needs to modify the maximum value of switch rule to a proper value

some MAC_VLAN rules in switch table, and as the number of rules increased,
the hash conflicts in the switch filter table are increased, so we can
