You can now configure LAG on VSC9953's ports using the command:
ethsw [port <port_no>] aggr {[help] | show | <lag_group_no>}
A port must belong to a single LAG. By default, a port
belongs to a LAG equal to the port's number.
For each frame, a hash will be calculated based on
Source/Destination MAC addresses, Source/Destination IP(v4/v6)
addresses, Source/Destination ports. This hash will be used to
select a single egress port from LAG. This also assures
that frames from the same flow will always have the
same egress port.

When IP is configured with pong buffers, IP is receiving packets to ping

Signed-off-by: Michal Simek <michal.simek@xilinx.com>
The original logic in the driver was exchanging buffers which are used for
sending packet and tx_ping and tx_pong buffers were exchanged all the
time to ensure that IP has enough time to send the packet out.
Based on this "feature" send function was using nextbuffertouse variable
to save which buffer should be used.
Before this algorithm was called driver checked that there is free
buffer available.
This checking remains in the driver but driver tries to use tx_ping
first if available. If not, tx_pong buffer is used instead.
To reach this code the original condition is met that at least one of the
buffer should be available.
