Ethernet RX DMA buffers are polled in NAPI work queue other than received
directly in DMA RX interrupt handler.

All drivers that select MII also need to select NET_CORE because MII
depends on it. This is a bit ridiculous because NET_CORE is just a
menu option that doesn't enable any code by itself.
There is also no need for it to be a visible option, since its users
all select it.

Commit 70ac618c07 ("ptp: fixup Kconfig for two PHC drivers.") removed all
dependencies for the blackfin hardware time-stamping Kconfig entry. Hardware
time-stamping is only available on BF518 though. Since the Kconfig entry is
'default y', just updateing your kernel source and running `make defconfig` will
result in the the following build errors:
drivers/net/ethernet/adi/bfin_mac.c:694: error: implicit declaration of function ‘bfin_read_EMAC_PTP_CTL’
drivers/net/ethernet/adi/bfin_mac.c:702: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FV3’
drivers/net/ethernet/adi/bfin_mac.c:712: error: implicit declaration of function ‘bfin_write_EMAC_PTP_CTL’
drivers/net/ethernet/adi/bfin_mac.c:717: error: implicit declaration of function ‘bfin_write_EMAC_PTP_FOFF’
...
This patch adds back the dependency on BF518, and since it does not make sense
to expose this config option when the blackfin MAC driver is not enabled also
restore the dependency on BFIN_MAC.

Ben Hutchings recently came up with a better way to handle the kconfig
dependencies for the PTP hardware clocks. This patch converts one new and
one older driver to the new scheme.

The BF518 has a PTP time unit that works in a similar way to other MAC
based clocks, like gianfar, ixp46x, and igb. This patch adds support for
using the blackfin as a PHC. Although the blackfin hardware does offer a
few ancillary features, this patch implements only the basic operations.
Compile tested only.

MII Kconfig option is apart of the core networking drivers and
by default NET_CORE is enabled so drivers selecting MII will
have MII enabled as well. It was found using the randconfig
option during testing, MII would be selected but NET_CORE
could be disabled. This caused a dependency error.
Resolved the dependency by selecting NET_CORE when MII is
selected.

Move the Analog Devices Inc driver into drivers/net/ethernet/adi/ and
make the necessary Kconfig and Makefile changes.
