Many thanks to Gerald and Frank at SysKonnect for working with us and making this possible! Yes, that's great news. Is there any chance to get a copy of data sheet for Yukon chips? I've tried hard to make Rx TCP/UDP checksum offload work but failed. ATM both Linux and OpenBSD use Rx IP checksum offload only but this driver enabled Rx checksum offload for TCP/UDP. So I guess there is somthing not listed in SK-NET Genesis data sheet. :-( Quick reading the source shows that this driver has the following issues. 1. Incomplete bus_dma(9) support. The driver uses BUS_SPACE_MAXADDR when it creates DMA tags which means its DMA supports any address without limitations. However, I'm sure Rx/Tx descriptors should reside in 4GB. So the driver wouldn't work on systems with 4GB memory. 2. Since the driver makes use of mbpool(9) it wouldn't work when bounce buffers are involved. In fact, I think the use of mbpool(9) is really bad as it lacks bus_dmamap_sync(9) operation. 3. Lack of ALTQ support. 4. The driver may not work on big-endian architectures. 5. The driver may not work on architectures with strict-alignment. Btw, new sk(4) is availabe at the following URL. Due to lack of documentation it doesn't support YukonII yet. http://people.freebsd.org/~yongari/sk/if_sk.c http://people.freebsd.org/~yongari/sk/if_skreg.h I'm still having sk0: watchdog timeout in my system and I'll try new sk driver. I will let you know if there is any issue.

Ganbold Did you use expeimental code in http://people.freebsd.org/~yongari/sk/sk_test/ ? If the driver still emit watchdong timeout I have no idea atm. I've never met such errors but I suffered from mbuf cluster leak on CURRENT. I believe the leak comes from kernel not sk(4) as it also happens em(4) on i386 SMP. When you see the error would you check mbuf status with netstat(1)? -- Regards, Pyun YongHyeon ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]
