netdev: bunch of drivers: avoid WARN at net/core/dev.c:1328
The drivers were touching net queue before it has been started, so without this patch, the drivers will potentially WARN at net/core/dev.c:1328. I don't have the hardware for the drivers below, so this patch is untested, and thus should be carefully peer reviewed. tc35815.c au1000_eth.c bfin_mac.c macb.c ^ The four drivers are using phylib, they're calling netif_start_queue() in open() callback. So trivially remove netif_tx_schedule_all(). Phylib will handle netif_carrier_*(). cpmac.c fec_mpc52xx.c fs_enet/fs_enet-main.c sh_eth.c ^ The same as above, but these were also needlessly calling netif_carrier_*() functions. So removed queue calls and also remove carrier calls, since phylib will handle it. fs_enet-main.c also didn't call netif_start_queue() at open(), this is fixed now.
