Description Jiri Pirko 2009-05-25 13:55:11 UTC

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.

How reproducible:
Always

Steps to Reproduce:
1. Set up bonding interface in mode alb
2. enslave 8139 NIC
  
Actual results:
# 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

Expected results:
NIC is enslaved without problems.
