Calling IPv4 specific inet_csk_route_req in tcp_check_req
is a bad idea and crashes machine on IPv6 connections, as reported
by Valdis Kletnieks

Also, all we are really interested in is the timestamp
option in the header, so calling tcp_parse_options()
with the "estab" set to false flag is an overkill as
it tries to parse half a dozen other TCP options.

We know whether timestamp should be enabled or not
using data from request_sock.

	for_each_netdev(net, dev)
		some_action();
	read_unlock(&dev_base_lock);

This patch introduces multiple group support for etsec2.0

Multiple group support is provided by mapping the set of enabled
queues to different groups and then programming the per group
regsiters imask, ievent, rstat, tstat.

The queues corresponding to a group are indicated by programming
isrg (interrupt steering) registers.

This patch introduces multiple Tx and Rx queues.
The incoming packets can be classified into different queues
based on filer rules (out of scope of this patch). The number
of queues enabled will be based on a DTS entries fsl,num_tx_queues
and fsl,num_rx_queues.

Although we are enabling multiple queues, the interrupt coalescing
is on per device level (etsec-1.7 doesn't support multiple rxics
and txics).

This patch introduces the group structure. The elements of this
structure are the interrupt lines, their corresponding names,
the register memory map.
The elements for this group are factored out from the gfar_private
structure. The introduction of group structure will help in

Currently, the support is present only for single group and
single tx/rx queues.

Moving forward if we want to support multiple queues, we need
