  Allowing "default" transfer mode values is a dangerous thing to do as

  and devices often use different values for the default and maximum PIO
  mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay
  programmed for higher PIO mode while device will use the lower PIO mode.

  There is no functionality loss as by using special IOCTLs device can
  still be programmed to "default" transfer modes (it is only useful for
  debugging/testing purposes anyway).

Using multiple cores in the same package to handle received traffic

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.
