ath(4) -> ifa_add_loopback_route: insertion failed

[Alex Torres]

Hi all,

Up on insertion of a atheros PCMCIA card:

  ath0 at pci0:3:0:0: class=0x020000 card=0x2051168c chip=0x0013168c rev=0x01
hdr=0x00
  vendor = 'Atheros Communications Inc.'
  device = '802.11a/b/g Wireless Adapter (AR5212)'
  class = network
  subclass = ethernet

I get the following in dmesg(8)

  ath0: <Atheros 5212> mem 0x88000000-0x8800ffff irq 18 at device 0.0 on
cardbus0
  ath0: [ITHREAD]
  ath0: AR2413 mac 7.9 RF2413 phy 4.5
  ifa_add_loopback_route: insertion failed

Can anyone shed any light as to what this means ? And why this is happening
?

Thanks
