`net` may not need to wait for the sequencer on Cosmo

[mkeeter]

On Cosmo, net waits for jefe to have a state assigned by cosmo_seq. This may not be necessary!

The comment refers to a clock generator that isn't present on Cosmo; we're using crystals for everything.

Lines 56 to 59 in 1e556d6

	fn preinit() {
	// Wait for the sequencer to turn on the clock. This requires that Jefe
	// state change notifications are routed to our notification bit 3.
	let jefe = Jefe::from(crate::JEFE.get_task_id());

It turns out this is necessary, but not for clock reasons: cosmo-seq is also responsible for loading data from the VPD EEPROM into packrat, which includes the board's MAC address. net wants to wait for the MAC address to be available before starting up.
