according to a comment in linux driver, reading Isrc2 register caused interrupts to be disabled. we used to read Isrc2 in ifstat() and it was confirmed that reading ifstat locks up ethernet. removing the Isrc2 read in ifstats, and also reenable interrupts after reading Isrc2 when the interrupt was not for us. (this is from the linux driver) in replenish(), set ring software write pointer (Sring.wp) *before* the hardware write index register. otherwise rx() could get status notification for completed receive but wont find the rx descriptor in the ring. handle uint wrap arround when calculating ring fill count and remaining count. |
