It seems to work with this one:
02:03.0 Ethernet controller: Intel Corp. 82557 [Ethernet Pro 100] (rev 02) Subsystem: IBM 82558B Ethernet Pro 10/100 Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 32 (2000ns min, 14000ns max) Interrupt: pin A routed to IRQ 16 Region 0: Memory at e0000000 (32-bit, prefetchable) [size=4K] Region 1: I/O ports at a400 [size=32] Region 2: Memory at df000000 (32-bit, non-prefetchable) [size=1M] Expansion ROM at <unassigned> [disabled] [size=1M]
No problem with more than 10^7 packets It just drops packets under heavy load, without live-locking, so NAPI kinda works :)
Unfortunally, I could not get this NIC to work with oversized frames to implement 802.1q, both with eepro100 and e100 drivers :(
:wq With best regards, Vladimir Savkin.
