Setup: MIPS board -> Hub <- RH 9 (DHCP server)
I have a RTL8139 based PCI NIC inserted on the MIPS?s PCI (2.1) slot. The WAL on the NIC is left floating (Is that a problem?). I am able to send packets from the MIPS board to RH 9, but the packets sent from the RH 9 is not reaching the MIPS board.
Even if the DHCP server is not connected, I see the Link status change interrupt (status) bit of ISR going high after every packet sent from the MIPS board. Seems like the cause for the problem I see, am I right? Can somebody tell me why the link status is changing after a packet is sent out?
Sample at every change in ISR: ----------------------------- BMCR = 0x1100 BMSR = 0x782d ANAR = 0x01e1 ANLPAR = 0x45e1 ANER = 0x0001 DIS = 0x0000 FCSC = 0x0000
Is there a register to look at, for the cause to this link status change <The above registers don't change at all>? Please suggest me a way to debug this issue.
Thanks, -Mike.
