The Network Coprocessor (NetCP) is a hardware accelerator that processes
Ethernet packets. 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.
