Link reset counter in data link reset state machine

[LeFl0w]

Spacefibre norm do not identify any wait state inside the state machine reset for link ( 5.7.9 Link Reset state machine ):

but in the associated state machine counters are implemented:

spacefibrelight/src/module_data_link/data_link_reset.vhd

Lines 115 to 121 in f8b7330

	-- FIXME : determine wy there are a reset counter which is not mentionned in 5.7.9
	if cnt_link_reset > 2 then
	cnt_link_reset <= (others =>'0');
	current_state <= NEAR_END_RST_ST;
	else
	cnt_link_reset <= cnt_link_reset+1;
	end if;

This has to be investigated
