It should be fine to set tx-frames default value to 1, so ptp4l will pass

This adds support for U32 filter by using an HW only feature called
Flexible RX Parser. This allow us to match any given packet field with a
pattern and accept/reject or even route the packet to a specific DMA
channel.

Right now we only support acception or rejection of frame and we only
support simple rules. Though, the Parser has the flexibility of jumping to
specific rules as an if condition so complex rules can be established.

This is only supported in GMAC5.10+.

The following commands can be used to test this code:

	1) Setup an ingress qdisk:
	# tc qdisc add dev eth0 handle ffff: ingress

	2) Setup a filter (e.g. filter by IP):
	# tc filter add dev eth0 parent ffff: protocol ip u32 match ip \
		src 192.168.0.3 skip_sw action drop

In every tests performed we always used the "skip_sw" flag to make sure
only the RX Parser was involved.

Broadcom tags inserted by Broadcom switches put a 4 byte header after
the MAC SA and before the EtherType, which may look like some sort of 0
length LLC/SNAP packet (tcpdump and wireshark do think that way). With
ACS enabled in stmmac the packets were truncated to 8 bytes on
reception, whereas clearing this bit allowed normal reception to occur.

In order to make that possible, we need to pass a net_device argument to
the different core_init() functions and we are dependent on the Broadcom
tagger padding packets correctly (which it now does). To be as little
invasive as possible, this is only done for gmac1000 when the network
device is DSA-enabled (netdev_uses_dsa() returns true).

The current stmmac_adjust_link() part which handle speed have
some if (has_platform) code and my dwmac-sun8i will add more of them.

So we need to handle better speed selection.
Moreover the struct link member speed and port are hard to guess their
purpose. And their unique usage are to be combined for writing speed.

So this patch replace speed/port by simpler
speed10/speed100/speed1000/speed_mask variables.

In dwmac4_core_init and dwmac1000_core_init, port/speed value was used
directly without using the struct link. This patch convert also their
usage to speedxxx.

however, to avoid relying on undefined behavior, set the length in TDES3.

The field has a different meaning depending on if the TSE bit in TDES3
is set or not (TSO). However, regardless of the TSE bit, the field is
not optional. The field is already set correctly when the TSE bit is set.

Since there is no limit for the number of descriptors that can be
used for a single packet, the field should be set to the sum of
the buffers contained in:
[<desc with First Descriptor bit set> ... <desc n> ...
<desc with Last Descriptor bit set>], which should be equal to skb->len.

Two different set_mac functions exists but stmmac_dwmac4_set_mac() is
only used for enabling and never for disabling.
So on dwmac4, the MAC RX/TX is never disabled.

This patch add a generic function pointer set_mac() to stmmac_ops and
replace all call to stmmac_set_mac/stmmac_dwmac4_set_mac by a call to
this pointer.

Since dwmac4_ops is const, set_mac cannot be modified after, and so dwmac4_ops
is duplioacted like dwmac4_dma_ops.
