NetCP has a gigabit Ethernet (GbE) subsystem with a ethernet switch sub-module to send and receive packets. NetCP also includes a packet accelerator (PA) module to perform packet classification operations such as header matching, and packet modification operations such as checksum generation. NetCP can also optionally include a Security Accelerator(SA) capable of performing IPSec operations on ingress/egress packets. Keystone SoC's also have a 10 Gigabit Ethernet Subsystem (XGbE) which includes a 3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates per Ethernet port. Both GBE and XGBE network processors supported using common driver. It is also designed to handle future variants of NetCP. version history --------------- v7->v8 - Reworked comments against v7, related to checker warning. - Patch 2/4 that has all of the driver code in v7 is now split into 3 patches based on functionality so that we have 3 smaller patches review instead of a big patch. - Patch for MAINTAINER is merged to 2/4 along with netcp core driver - Separate patch (3/4) for 1G and (4/4) for 10G - Removed big endian support for initial version (will add it later) v6->v7 - Fixed some minor documentation error and also modified the netcp driver to fix the set* functions to include correct le/be macros. v5->v6 - updated version after incorporating comments [6] from David Miller, David Laight & Geert Uytterhoeven on v5. I would like get this in for v3.19 merge window if the latest version is acceptable. v4->v5 - Sorry to spin v5 quickly but I missed few check-patch warnings which were pointed by Joe Perches(thanks). I folded his changes [5] along with few more check-patch warning fixes. I would like get this in for v3.18 merge window if David is happy with this version. v3->v4 - Couple of fixes in in error path as pointed [4] out by David. Rest of the patches are unchanged from v3. v2->v3 - Update v3 after incorporating Jamal and David Miller's comment/suggestion from earlier versions [1] [2]. After per the discussion here [3], the controversial custom exports have been dropped now. And for future future offload support additions, we will plug into generic frameworks as an when they are available.
