Notice the 4 bytes of 0 before the expected byte of d0.

Databook notes that the RX buffer must be a multiple of 4/8/16

Update the DMA Buffer size define to 8188 instead of 8192. Remove
the -1 from the RX buffer size allocations and use the new
DMA Buffer size directly.

      net: stmmac: Rework coalesce timer and fix multi-queue races · 8fce3331
      由 Jose Abreu 提交于 
      This follows David Miller advice and tries to fix coalesce timer in
multi-queue scenarios.

We are now using per-queue coalesce values and per-queue TX timer.

Coalesce timer default values was changed to 1ms and the coalesce frames
to 25.

Tested in B2B setup between XGMAC2 and GMAC5.

      net: stmmac: Add Flexible PPS support · 9a8a02c9
      由 Jose Abreu 提交于 
      This adds support for Flexible PPS output (which is equivalent
to per_out output of PTP subsystem).

Tested using an oscilloscope and the following commands:

1) Start PTP4L:
	# ptp4l -A -4 -H -m -i eth0 &
2) Set Flexible PPS frequency:
	# echo <idx> <ts> <tns> <ps> <pns> > /sys/class/ptp/ptpX/period

Where, ts/tns is start time and ps/pns is period time, and ptpX is ptp
of eth0.

      net: stmmac: Add support for U32 TC filter using Flexible RX Parser · 4dbbe8dd
      由 Jose Abreu 提交于 
      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.

      net: stmmac: Implement logic to automatically select HW Interface · 5f0456b4
      由 Jose Abreu 提交于 
      Move all the core version detection to a common place ("hwif.c") and
implement a table which can be used to lookup the correct callbacks for
each IP version.

This simplifies the initialization flow of each IP version and eases
future implementation of new IP versions.

      net: stmmac: Add support for DWMAC5 and implement Safety Features · 8bf993a5
      由 Jose Abreu 提交于 
      This adds initial suport for DWMAC5 and implements the Automotive Safety
Package which is available from core version 5.10.

The Automotive Safety Pacakge (also called Safety Features) offers us
with error protection in the core by implementing ECC Protection in
memories, on-chip data path parity protection, FSM parity and timeout
protection and Application/CSR interface timeout protection.

In case of an uncorrectable error we call stmmac_global_err() and
reconfigure the whole core.

      net: stmmac: Fix reception of Broadcom switches tags · 8cad443e
      由 Florian Fainelli 提交于 
      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).

      net-next: stmmac: rework the speed selection · ca84dfb9
      由 LABBE Corentin 提交于 
      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.

      net: stmmac: set total length of the packet to be transmitted in TDES3 · fe6af0e1
      由 Niklas Cassel 提交于 
      Field FL/TPL in register TDES3 is not correctly set on GMAC4.
TX appears to be functional on GMAC 4.10a even if this field is not set,
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.
