The patch series adds Solarflare libefx-based network PMD.
This version of the driver supports Solarflare SFN7xxx and SFN8xxx
families of 10/40 Gbps adapters.
libefx is a platform-independent library to implement drivers for
Solarflare network adapters. It provides unified adapter family
independent interface (if possible). FreeBSD [1] and illumos [2]
drivers are built on top of the library.
The patch series could be logically structured into 5 sub-series:
1. (1) add the driver skeleton including documentation
2. (2-30) import libefx and include it in build with the latest patch
3. (31-42) implement minimal device level operations in steps
4. (43-50) implement Rx subsystem
5. (51-55) implement Tx subsystem
Functional driver with multi-queue support capable to send and receive
traffic appears with the last patch in the series.
The following design decisions are made during development:
1. Since libefx uses positive errno return codes, positive errno
return codes are used inside the driver and coversion to negative
is done on return from eth_dev_ops callbacks. We think that it
is the less error-prone way.
2. Own event queue (a way to deliver events from HW to host CPU) is
used for house-keeping (e.g. link status notifications), each Tx
and each Rx queue. No locks on datapath are requires in this case.
3. Alarm is used to periodically poll house-keeping event queue.
The event queue is used to deliver link status change notifications,
Rx/Tx queue flush events, SRAM events. It is not used on datapath.
The event queue polling is protected using spin-lock since
concurrent access from different contexts is possible (e.g. device
stop when polling alarm is running).
