  Called rte_eth_dev_info_get() in testpmd, to get device info
so that speed capabilities can be printed under "show device info"

How about extracting the below to a dedicated helper function to make the code more readable?
Something like: void device_infos_display_speeds(uint32_t speed_capa)

I'm ok also to leave is as-is.

Some speeds are missing, please add all.

And +1 to Asaf's comment to extract it into its own function.
