  The majority of "ethdev" type functions are used for both PF devices and
VF devices. Prototype these functions in the nfp_net_pmd header file in
preparation of splitting PF and VF specific functions.

Following functions seems only used in this file, and you may want to keep them
'static':
nfp_net_dev_link_status_print
nfp_net_irq_unmask
nfp_net_dev_interrupt_delayed_handler
nfp_net_rss_reta_write
nfp_net_rss_hash_write

(I may be missed some, you may want to double check all.)

Rest of the set looks good to me.

Thanks,
ferruh

Since rest is OK, I will make above functions static while merging, if they
needs to be used by other files they can always be updated again.
