We should really use dev_dbg() instead, as it retains the 'ethX:' annotation afaics. I'll have to see what looks best and also handle e100 and e1000.

(CC netdev since it's a network driver topic). all our macro's (e100, e1000, ixgb) use adapter->netdev->name inserted through the DPRINTK macro. if you'd really want to clean it all up, you'd have to replace all DPRINTK() calls with dev_dbg(adapter->netdev->name, ....) which would just make it more lengthy and uncomfortable to read. which puts this in a bigger perspective. I suppose the nicest way to do program these is to do something like this: #define ixgb_dbg(args...) dev_dbg(adapter->netdev->name, args) #define ixgb_err(args...) dev_err(adapter->netdev->name, args) #define ixgb_info(args...) dev_info(adapter->netdev->name, args) and use those consistently throughout the driver, ditto for e100/e1000. I'll look into it and see what I can do. Cheers, Auke ^ permalink raw reply [flat|nested] 9+ messages in thread

That's a lot of information when we really only care about 'eth0: ' perhaps with 'ixgb: ' prepended to it. You end up with pretty much the same code that was there before - unless we make something common for netdevices and use that instead: #define netdev_dbg(netdev, args...) pr_debug(netdev->name, args) and then use this stacked in the driver: #define ixgb_dbg(args...) netdev_dbg(adapter->netdev, args) that would seem clean and appropriate, and since this bit of infrastructure is missing from netdevice.h, explains the current situation in all netdrivers (chaos). of course, I'm completely not taking netif_msg_level into account yet here, which probably makes it a bit more hairy.
