Error description
A network performance degradation occurs on FC5899 adapter. The problem is that missing interrupts occur for receiving packets. The delay becomes more than 100msec for each packet and retransmissions occur. The packets remain in the adapter, and they are handled when another interrupt for another packet is raised.
Local fix
