This patch stops the internal MAC Tx clock from being enabled as the
internal clock isn't used. The definition used for the bit controlling
this behaviour is renamed as well as it was wrongly named (bit 4 of
GMAC_CTRL_2_REG).

The private port_list array has a list of pointers to mvpp2_port
instances. This list is allocated given the number of ports enabled in
the device tree, but the pointers are set using the port-id property. If
on a single port is enabled, the port_list array will be of size 1, but
when registering the port, if its id is not 0 the driver will crash.
Other crashes were encountered in various situations.

This fixes the issue by using an index not equal to the value of the
port-id property.

- refactors link up/down condition and introduces dmesg log event when

If MTU is changed the host would reject the send buffer change.
This problem is result of recent change to allow changing send
buffer size.

Every time we change the MTU, we store the previous net_device section
count before destroying the buffer, but we don’t store the previous
section size. When we reinitialize the buffer, its size is calculated
by multiplying the previous count and previous size. Since we
continuously increase the MTU, the host returns us a decreasing count
value while the section size is reinitialized to 1728 bytes every
time.

This eventually leads to a condition where the calculated buf_size is
so small that the host rejects it.

This patch is pretty much a carbon copy of
commit 3079c652 ("caif: Fix napi poll list corruption")
with "caif" replaced by "emac".

The commit d75b1ade ("net: less interrupt masking in NAPI")
breaks emac.

It is now required that if the entire budget is consumed when poll
returns, the napi poll_list must remain empty.  However, like some
other drivers emac tries to do a last-ditch check and if there is
more work it will call napi_reschedule and then immediately process
some of this new work.  Should the entire budget be consumed while
processing such new work then we will violate the new caller
contract.

This patch fixes this by not touching any work when we reschedule

When there is no vlan id in the packets, hardware will treat the vlan id
as 0 and look for the mac_vlan table. This patch set the default vlan id
of PF as 0. Without this config, it will fail when look for mac_vlan
table, and hardware will drop packets.
