Some dual port PHY require HW lock since they are used by both interfaces (different driver instances). Since this list is getting longer, update a parameter at load time instead of calculating it on runtime Signed-off-by:

Also adding the ability to recognize the optic module and disable it if it is not authorized for safety reasons - since this feature might upset some users which are willing to take the risk, it is optional and can be disabled by setting an nvram bit (or a trivial driver patch to set this bit). This dual port PHY requires special handling if the ports are swapped. Signed-off-by:

Before initializing the chip after iSCSI boot, the interrupts of the function that was used to boot must be disabled. That means that the driver needs to set the chip as if it is the iSCSI PCI function - this bug is exposed only with MSI Signed-off-by:

Enabling MSI on top of MSI-X and INTA. Also changing the module parameter to allow choosing INTA or MSI even when MSI-X is available. The default status block should not be reversed for endianity. Since MSI can issue re-configuration, the interrupt disable function now requires mmiowb Signed-off-by:

This is the FW blob and the relevant definitions without any logic. It also contains the minimal mandatory code changes to work with this FW but it does not contain enabling of the new features that this FW provides. This FW is needed for: - More efficient multi-queue - per queue statistics - Big-endian issue with MSI - Improved pause response Signed-off-by:

Both TX and RX hardware time stamping are implemented. Due to hardware limitations it is not possible to verify reliably which packet was time stamped when multiple were pending for sending; this could be solved by only allowing one packet marked for hardware time stamping into the queue (not implemented yet). RX time stamping relies on the flag in the packet descriptor which marks packets that were time stamped. In "all packet" mode this flag is not set. TODO: also support that mode (even though it'll suffer from race conditions). Signed-off-by:

The overlap with the old SO_TIMESTAMP[NS] options is handled so that time stamping in software (net_enable_timestamp()) is enabled when SO_TIMESTAMP[NS] and/or SO_TIMESTAMPING_RX_SOFTWARE is set. It's disabled if all of these are off. Signed-off-by:

The additional per-packet information (16 bytes for time stamps, 1 byte for flags) is stored for all packets in the skb_shared_info struct. This implementation detail is hidden from users of that information via skb_* accessor functions. A separate struct resp. union is used for the additional information so that it can be stored/copied easily outside of skb_shared_info. Compared to previous implementations (reusing the tstamp field depending on the context, optional additional structures) this is the simplest solution. It does not extend sk_buff itself. TX time stamping is implemented in software if the device driver doesn't support hardware time stamping. The new semantic for hardware/software time stamping around ndo_start_xmit() is based on two assumptions about existing network device drivers which don't support hardware time stamping and know nothing about it: - they leave the new skb_shared_tx unmodified - the keep the connection to the originating socket in skb->sk alive, i.e., don't call skb_orphan() Given that skb_shared_tx is new, the first assumption is safe. The second is only true for some drivers. As a result, software TX time stamping currently works with the bnx2 driver, but not with the unmodified igb driver (the two drivers this patch series was tested with). Signed-off-by:

User space can request hardware and/or software time stamping. Reporting of the result(s) via a new control message is enabled separately for each field in the message because some of the fields may require additional computation and thus cause overhead. User space can tell the different kinds of time stamps apart and choose what suits its needs. When a TX timestamp operation is requested, the TX skb will be cloned and the clone will be time stamped (in hardware or software) and added to the socket error queue of the skb, if the skb has a socket associated with it. The actual TX timestamp will reach userspace as a RX timestamp on the cloned packet. If timestamping is requested and no timestamping is done in the device driver (potentially this may use hardware timestamping), it will be done in software after the device's start_hard_xmit routine.

Mapping from a struct timecounter to a time returned by functions like ktime_get_real() is implemented. This is sufficient to use this code in a network device driver which wants to support hardware time stamping and transformation of hardware time stamps to system time. The interface could have been made more versatile by not depending on a time counter, but this wasn't done to avoid writing glue code elsewhere. The method implemented here is the one used and analyzed under the name "assisted PTP" in the LCI PTP paper: http://www.linuxclustersinstitute.org/conferences/archive/2008/PDF/Ohly_92221.pdfAcked-by:
