&rxbd[0] is a virtual address.

Doesn't rbase require a physical address? You're assuming that virt == phys.

Also:

• out_be32(&regs->tbase, (unsigned int)(&rtx.txbd[tx_idx]));
• out_be32(&regs->rbase, (unsigned int)(&rtx.rxbd[rx_idx]));

• out_be32(&regs->tbase, (u32)&txbd[0]);
• out_be32(&regs->rbase, (u32)&rxbd[0]);

Are you assuming that rx_idx will always be zero in this case?

Hi,

This is just initialization code, rx_idx and tx_idx are set to 0 just 4-5 irrelevant lines above (unfortunately format-patch doesn't catch that in the patch's context).

Thanks, Claudiu
