Subject: RE: [PATCH 2/2] Fix phy_attach - forward dev_flags for phy_attach

> By the way, most, if not all of the phy_connect() users in drivers/net/ethernet/ also do not ensure they pass the phy device flags, so you might 

want to fix this globally and not just for Marvell driver.
Indeed, phy_connect() mostly just pass zero intead of phy_dev->dev_flags.
But, I think, the guy that calls phy_connect() in its driver should know what he does, and,
probably, we should rely on him knowing his stuff.
The only evidence of the bug is when phy_dev->dev_flags was actually changed by PHY fixup callback
(see dns323-setup.c for example) and was *not* propagated to phy_connect() or phy_attach() as in pxa168_eth.c phy_init().
The code conforming to the former should be fixed IMHO.

Thanks,
