dl2k: Add support for IP1000A-based cards
Add support for IP1000A chips to dl2k driver. IP1000A chip looks like a TC9020 with integrated PHY. This allows IP1000A chips to work reliably because the ipg driver is buggy - it loses packets under load and then completely stops transmitting data. Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps: vendor=0x13f0 device=0x1023 (rev 0x41) subsystem vendor=0x1043 device=0x8180 MAC address registers access needed to be changed from 8-bit to 16-bit because 8-bit does not work on IP1000A. 8-bit access is not even allowed in the TC9020 datasheet (although it worked). 16-bit access works on both. Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably a rebranded TC9020): vendor=0x1186 device=0x4000 (rev 0x0c) subsystem vendor=0x1186 device=0x4000 Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: David S.
