Subject: [PATCH net-next v2 00/10] nfp: support for NFP-3800
Hi,
Yinjun Zhan says:
This is the second of a two part series to support the NFP-3800 device.
To utilize the new hardware features of the NFP-3800, driver adds support
of a new data path NFDK. This series mainly does some refactor work to the
data path related implementations. The data path specific implementations
are now separated into nfd3 and nfdk directories respectively, and the
common part is also moved into a new file.
* The series starts with a small refinement in Patch 1/10. Patches 2/10 and
3/10 are the main refactoring of data path implementation, which prepares
for the adding the NFDK data path.
* Before the introduction of NFDK, there's some more preparation work
for NFP-3800 features, such as multi-descriptor per-packet and write-back
mechanism of TX pointer, which is done in patches 4/10, 5/10, 6/10, 7/10.
* Patch 8/10 allows the driver to select data path according
to firmware version. Finally, patches 9/10 and 10/10 introduce the new
NFDK data path.
Changes between v1 and v2
* Correct kdoc for nfp_nfdk_tx()
* Correct build warnings on 32-bit
Thanks to everyone who contributed to this work.
Jakub Kicinski (9):
nfp: calculate ring masks without conditionals
nfp: move the fast path code to separate files
nfp: use callbacks for slow path ring related functions
nfp: prepare for multi-part descriptors
nfp: move tx_ring->qcidx into cold data
nfp: use TX ring pointer write back
nfp: add per-data path feature mask
nfp: choose data path based on version
nfp: add support for NFDK data path
