	Gate list, or nullptr when count is 0.
uint16_t	count
	Entries for this queue (EATASENCi).

Detailed Description

The gate-control list of one descriptor queue.

Each of the eight descriptor queues owns a contiguous block of TAS RAM entries; EATASENCi.TASAEN records how many entries queue i has (HUM Ch 32.3.5.3 p 1647). A queue with count == 0 is left out of the schedule entirely and its entries pointer is never dereferenced.

Invariant

entries is non-null whenever count is non-zero.

The sum of count over all queues is at most k_ra8_etha_tas_entries_max.
