Log:
Add preliminary support for the RealTek 8169 gigE chip. Changes:
- Fix a bug in rl_dma_map_desc(): set the 'end of ring' bit in the
right descriptor (DESC_CNT - 1, not DESC_CNT). The 8139C+ is limited
to 64 descriptors and automatically wraps at 64 descriptors even
if the EOR bit isn't set, but the 8169 NIC can have up to 1024
descriptors per ring, so we must set the wrap point in the right
place.
- RealTek moved the RL_TIMERINT register from offset 0x54 to 0x58 in
the 8169 -- account for this.
- Added rl_gmii_readreg() and rl_gmii_writereg() routines.
- Fix rl_probe() to deal with the case where the base type is
not RL_8139.
The next step is to add jumbo buffer support.
Tested with the Xterasys XN-152 NIC (hard to beat $29 for a gigE NIC).
