There is no 'CONFIG_RTE_LIBRTE_ARK_MIN_TX_PKTLEN' option, I think it is
confusing to add it to documentation. There is already some documentation in
below for 'RTE_LIBRTE_ARK_MIN_TX_PKTLEN', what do you think removing this part?

And can you please remove 'CONFIG_RTE_LIBRTE_ARK_PAD_TX' form 'config/common_base'?

Another option is, do you think does it help your users to keep the config name
same, like keep the 'CONFIG_RTE_LIBRTE_ARK_PAD_TX' as 'RTE_LIBRTE_ARK_PAD_TX'
for the meson CFLAGs, instead of renaming it to 'RTE_LIBRTE_ARK_MIN_TX_PKTLEN'?
