This patch adds support for frames splited between
many rx buffers. Header data spliting can be used
but also buffers shorter than max frame length.
The only limitation is that frame header can't
be splited.

This patch series adds support for receive packets
filtering for Cadence GEM driver. Packets can be redirect
to different hardware queues based on source IP, destination IP,
source port or destination port. To enable filtering,
support for RX queueing was added as well.

There are many IP cores with many configuration. If it is possible,
capabilities should be read from IP directly.
And it is possible in that case:
Design Configuration Register 5 (0x290)
bit 8: tsu
There is now PTP hardware support without that bit.

In macb_start_xmit() there is also invoked skb_tx_timestamp() for software

I think, it should be disabled if you do hardware timestamping.

I know that those are different locks and different types. But this could lead
to deadlocks. This is the reason of warning I could see.
And this is the reason why I get timestamp in interrupt routine but pass it to
skb outside interrupt (using circular buffer).

You enable 64 bit addressing (64b dma bus width) always when appropriate
architecture config option is enabled.
But there are some legacy controllers w
