This patch set enables,
(i) Classifier engine that is used for parsing
through the packet and extracting a search string that is then used
to search a database to find associative data.
(ii) Receive Side Scaling (RSS) that does dynamic load
balancing of the CPUs by controlling the number of messages enqueued
per CPU though the help of Toeplitz Hash function of 4-tuple of
source TCP/UDP port, destination TCP/UDP port, source IPV4 address and
destination IPV4 address.
(iii) Multi queue, to make advantage of RSS
v3: Address review comments from v2
- reordered local variables from longest to shortlest line
v2: Address review comments from v1
- fix kbuild warning
- add default coalescing
v1:
- Initial version
