This series adds support for Realtek's RTL8365MB-VC, a 4+1 port
10/100/1000M Ethernet switch. The driver - rtl8365mb - was developed by
Michael Ramussen and myself.
This version of the driver is relatively slim, implementing only the
standalone port functionality and no offload capabilities. It is based
on a previous RFC series [1] from August, and the main difference is the
removal of some spurious VLAN operations. Otherwise I have simply
addressed most of the feedback. Please see the respective patches for
more detail.
In parallel I am working on offloading the bridge layer capabilities,
but I would like to get the basic stuff upstreamed as soon as possible.
v3 -> v4:
- get irq before setting virq parents (fixes kernel test robot
warning)
- remove pad-to-72-bytes logic in tagger xmit (fixes DENG Qingfang's
suggestion); no longer needed as we set CPU minimum RX size to 64
bytes
- use mutex to protect MIB counter access instead of a spinlock (fixes
Jakub's feedback on v3 statistics refactoring)
v2 -> v3:
- move IRQ setup earlier in probe per Florian's suggestion
- fix compilation error on some archs due to FIELD_PREP use in v1
- follow Jakub's suggestion and use the standard ethtool stats API;
NOTE: new patch in the series for relevant DSA plumbing
- following the stats change, it became apparent that the rtl8366
helper library is no longer that helpful; scrap it and implement
the ethtool ops specifically for this chip
v1 -> v2:
- drop DSA port type checks during MAC configuration
- use OF properties to configure RGMII TX/RX delay
- don't set default fwd_offload_mark if packet is trapped to CPU
- remove port mapping macros
- update device tree bindings documentation with an example
- cosmetic changes to the tagging driver using FIELD_* macros
