qcacld-2.0 to qcacmn propagation
This change adds support for driver supported TCP
delayed ack to increase TCP RX performance in
third-party platform which don't support kernel
TCP delayed ack feature.
TCP delayed ack is dependent on count and timer
values. Whatever is achieved first will trigger
sending TCP ack.
This feature can be controlled through ini values.
gDriverDelAckTimerValue - timer value in ms
gDriverDelAckPktCount - delayed ack count
gDriverDelAckEnable - enable/disable feature

With this feature, using appropriate commands, link layer, network layer,
transport layer and some of the application protocols can be tagged with
the user provided tag values for easier identification of protocols. The
supported protocols today are as follows.
ARP, DHCPv4, DHCPv6, DNS over TCP (v4), DNS over TCP (v6), DNS over UDP
(v4), DNS over UDP (v6), ICMPv4, ICMPv6, TCPv4, TCPv6, UDPv4,
UDPv6, IPv4, IPv6, EAP.
Receive packets are tagged by hardware. Tags are applied after the first
matching rule. Hence it is recommended that the rules are
programmed in such a way that tags are configured from application layer
to data link layer to get expected results.
