The jumbo frame uses the 'RTE_ETHER_MAX_LEN' as boundary condition, but
the Ether overhead is larger than 18 when it supports dual VLAN tags.
That will cause the jumbo flag rx offload is wrong when MTU size is
'RTE_ETHER_MTU'.
This fix will change the boundary condition with 'RTE_ETHER_MTU' and
overhead.
Fixes: 84dc7a95a2d3 ("net/ice: enable flow director engine")
Fixes: 1b009275e2c8 ("net/ice: add Rx queue init in DCF")
Fixes: ae2bdd0219cb ("net/ice: support MTU setting")
Fixes: 50370662b727 ("net/ice: support device and queue ops")
