z8530_tx_begin - Begin packet transmission

DESCRIPTION¶

This is the speed sensitive side of transmission. If we are called and no buffer is being transmitted we commence the next buffer. If nothing is queued we idle the sync.

We are handling this code path in the interrupt path, keep it fast or bad things will happen.

Called with the lock held.
