Subject: Pull request: sfc-next 2013-03-11

The following changes since commit 6906f4ed6f85b2d72fd944e15da6a905fdde8b40:

  htb: add HTB_DIRECT_QLEN attribute (2013-03-06 15:40:53 -0500)

(commit 1648a23fa159e5c433aac06dc5e0d9db36146016)

1. Merge sfc changes (only) accepted for 3.9.

2. PTP improvements from Laurence Evans.

3. Overhaul of RX buffer management:
- Always allocate pages, and enable scattering where possible
- Fit as many buffers as will fit into a page, rather than limiting to 2
- Introduce recycle rings to reduce the need for IOMMU mapping and
  unmapping

4. PCI error recovery (AER and EEH) implementation.

5. Fix a bug in RX filter replacement.

6. Fix configuration with 1 RX queue in the PF and multiple RX queues in
VFs.

Ben.
