Red Hat Bugzilla – Bug 502491
rtl8139 doesn't work with bonding in alb mode
Last modified: 2015-05-04 21:16:56 EDT
Description of problem:
NICs with chip Realtek 8139 are unable to change address when the interface is up. This causes that these NICs cannot be enslaved to bonding interface in alb mode which requires this functionality.
Steps to Reproduce:
1. Set up bonding interface in mode alb
2. enslave 8139 NIC
# ifenslave bond0 eth0
Master 'bond0', Slave 'eth0': Error: Enslave failed
fragment from dmesg:
eth0: link up, 100Mbps, full-duplex, lpa 0xC5E1
bonding: bond0: Error: dev_set_mac_address of dev eth0 failed! ALB mode requires that the base driver support setting the hw address also when the network device's interface is open
NIC is enslaved without problems.
