All ether_addr_equal tests in i40e can use the
slightly more efficient ether_addr_equal_64bits.
All addresses passed to the various functions that
use ether_addr_equal are using structs that have 2
or more bytes of additional data after the mac addr
being tested.

Some hotkeys don't work for perf top so split help messages for them.
It'll be helpful to a future modification. Also sort the message by

Sometimes perf top TUI breaks display with concurrent help/input window

You can check it by pressing (and not releasing) 'h' key on a "perf top
