NetXen network interfaces fail to receive or send packets after boot until they are restarted manually

Solution Verified - Updated -

Issue

  • netxen_nic interfaces fail to receive or send packets after boot until they are restarted manually. Issue is seen with both bonding and non-bonding environment.

  • When having at least one netxen network card in a bond, the bond doesn't work after boot. Restarting the interface with "ifdown bond0; ifup bond0" works around the problem.

  • The system appears to boot without issue and gives no indication of a network issue, however no network connectivity is available when using the netxen_nic at boot. But performing a "service network restart" or 'ifup', it brings up the interfaces and the network works perfectly from this point forward.

Environment

  • Red Hat Enterprise Linux 5 (RHEL5)

  • NetXen NIC using 'netxen_nic' driver
