All,
I am running 2.6.11 version of the kernel on MPC8541. Have one of the TSECs
configured at 100Mbps/Full Duplex. The TSEC MAC is connected to a Marvell
Ethernet switch MAC without any PHY in between. MAC level flow control is
enabled but no pause frames sent or received.
I see a high number of transmit buffer overrun errors (tx_fifo_empty errors
in the gianfar driver). I don't have NAPI enabled. In addition to other
things, I was thinking of enabling NAPI and see if it helps - is there any
downside to it?? Are there any other parameters that I could tweak to
reduce/eliminate the overrun errors??
Thanks,
Shriram.
