NAME
z8530_rx_done - Receive completion callback
SYNOPSIS
void z8530_rx_done(struct z8530_channel * c);
ARGUMENTS
- c
- The channel that completed a receive
DESCRIPTION
A new packet is complete. Our goal here is to get back into receive
mode as fast as possible. On the Z85230 we could change to using ESCC
mode, but on the older chips we have no choice. We flip to the new
buffer immediately in DMA mode so that the DMA of the next frame can
occur while we are copying the previous buffer to an sk_buff
