Marvell Prestera 98DX326x integrates up to 24 ports of 1GbE with 8
ports of 10GbE uplinks or 2 ports of 40Gbps stacking for a largely
wireless SMB deployment.
Prestera Switchdev is a firmware based driver which operates via PCI bus. The
current implementation supports only boards designed for the Marvell Switchdev
solution and requires special firmware.
This driver implementation includes only L1, basic L2 support, and RX/TX.
The core Prestera switching logic is implemented in prestera.c, there is
an intermediate hw layer between core logic and firmware. It is
implemented in prestera_hw.c, the purpose of it is to encapsulate hw
related logic, in future there is a plan to support more devices with
different HW related configurations.
The following Switchdev features are supported:
- VLAN-aware bridge offloading
- VLAN-unaware bridge offloading
- FDB offloading (learning, ageing)
- Switchport configuration
RFC v2:
1) Use "pestera_" prefix in struct's and functions instead of mvsw_pr_
2) Original series split into additional patches for Switchdev ethtool
support.
3) Use major and minor firmware version numbers in the firmware image
filename.
4) Removed not needed prints.
5) Use iopoll API for waiting on register's value in prestera_pci.c
6) Use standart approach for describing PCI ID matching section instead of
using
custom wrappers in prestera_pci.c
7) Add RX/TX support in prestera_rxtx.c.
8) Rewritten prestera_switchdev.c with following changes:
- handle netdev events from prestera.c
- use struct prestera_bridge for bridge objects, and get rid of
struct prestera_bridge_device which may confuse.
- use refcount_t
9) Get rid of macro usage for sending fw requests in prestera_hw.c
10) Add base_mac setting as module parameter. base_mac is required for
generation default port's mac.
