According API 'max_rx_pkt_len' is 'Only used if JUMBO_FRAME enabled'
Although not sure that is practically what is done for all drivers.

'rte_eth_dev_configure()' is one of the first APIs called, it is called before 
'rte_eth_dev_set_mtu().

When 'rte_eth_dev_configure()' is called, MTU is set to '1500' by default by 
ethdev layer, so it is not user configuration, but 'max_rx_pkt_len' is.

And later, when 'rte_eth_dev_set_mtu()' is called, but MTU and 'max_rx_pkt_len' 
are updated (mostly).

The 'max_rx_ptk_len' is annoyance for a long time, what do you think to just 
drop it?

By default device will be up with default MTU (1500), later 
'rte_eth_dev_set_mtu' can be used to set the MTU, no frame size setting at all.

Will this work?



And for short term, for above Intel PMDs, there must be a place this 
'max_rx_pkt_len' value taken into account (mostly 'start()' dev_ops), that 
function can be updated to take 'max_rx_pkt_len' only if JUMBO_FRAME set, 
otherwise use the 'MTU' value.

Without 'start()' updated the current logic won't work after stop & start anyway.
