In the BE3 FW image, unlike Skyhawk's, the "asic_type_rev" field doesn't track the asic_rev of chip it is compatible with. When asic_type_rev is 0 the image is compatible only with pre-BE3-R chips (asic_rev < 0x10). Fix the current compatibility check to take care of this. We hit this issue when we try to flash old BE3 images (used prior to the release of BE3-R) on pre-BE3-R adapters.

commit afae5ad7 "net/fsl_pq_mdio: streamline probing of MDIO nodes" added support for different types of MDIO devices: 1) Gianfar MDIO nodes that only map the MII registers 2) Gianfar MDIO nodes that map the full MDIO register set 3) eTSEC2 MDIO nodes (which map the full MDIO register set) 4) QE MDIO nodes (which map only the MII registers) However, the implementation for types 1 and 4 would mistakenly assume a mapping of the full MDIO register set, thereby computing the address for the TBI register starting from the containing structure. The TBI register would therefore be accessed at a wrong (much bigger) address, not giving the expected result at all. This patch restores the correct behavior we had prior to the above one. The consequences of this bug are apparent when trying to access a PHY with the same address as the value contained in the initial value of the TBI register (normally 0); in that case you'll get answers from the internal TBI device (even though MDIO/MDC pins are actually *also* toggling on the physical bus!). Beware that you also need to add a fake tbi node to your device tree with an unused address. Notice how this fix is related to commit 22066949 "powerpc: Add TBI PHY node to first MDIO bus" which fixed the behavior in kernel 3.3, which was later broken by the above commit on kernel 3.7.

When configuring the MDIO subsystem it is also necessary to configure the TBI register. Make sure the TBI is contained within the mapped register range in order to: a) make sure the address is computed correctly b) make users aware that we're actually accessing that register In case of error, print a message but continue anyway.

Joe Stringer says: ==================== OVS conntrack fixes for net The userspace side of the Open vSwitch conntrack changes is currently undergoing review, which has highlighted some minor bugs in the existing conntrack implementation in the kernel, as well as pointing out some future-proofing that can be done on the interface to reduce the need for additional compatibility code in future. The biggest changes here are to the userspace API for the ct_state match field and the CT action. This series proposes to firstly extend the ct_state match field to 32 bits, ensuring to reject any currently unsupported bits. Secondly, rather than representing CT action flags within a 32-bit field, simply use a netlink attribute as presence of the single flag that is defined today. This also serves to reject unsupported ct action flag bits. v4: Use 12-character abbreviated hashes in commit messages. v3: Fully acked. v2: Address minor style feedback, add acks. v1: Initial post. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Previously, the CT_ATTR_FLAGS attribute, when nested under the OVS_ACTION_ATTR_CT, encoded a 32-bit bitmask of flags that modify the semantics of the ct action. It's more extensible to just represent each flag as a nested attribute, and this requires no additional error checking to reject flags that aren't currently supported.

The ct_state field was initially added as an 8-bit field, however six of the bits are already being used and use cases are already starting to appear that may push the limits of this field. This patch extends the field to 32 bits while retaining the internal representation of 8 bits. This should cover forward compatibility of the ABI for the foreseeable future. This patch also reorders the OVS_CS_F_* bits to be sequential.

Previously, if userspace specified ct_state bits in the flow key which are currently undefined (and therefore unsupported), then they would be ignored. This could cause unexpected behaviour in future if userspace is extended to support additional bits but attempts to communicate with the current version of the kernel.
