This patch adds hardware channel APIs support between VF and PF for tunnelling configuration for the VFs.

2017-04-06qed: Don't close the OUT_EN during initMintz, Yuval1-12/+0
Before initializing the chip's engine, driver currently closes a set of registers on the HW's ingress flow to prevent packets from slipping in while they're not supposed to. This configuration is insufficient, as there are some scenarios where packets would still arrive even when said registers are set, but the management firmware already closes other per-port registers that do suffice, making this setting unnecessray.

2017-04-06qed: Don't use main-ptt in unrelated flowsRahul Verma8-61/+124
In order to access HW registers driver needs to acquire a PTT entry [mapping between bar memory and internal chip address]. Since acquiring PTT entries could fail [at least in theory] as their number is finite and other flows can hold them, we reserve special PTT entries for 'important' enough flows - ones we want to guarantee that would not be susceptible to such issues. One such special entry is the 'main' PTT which is meant to be used in flows such as chip initialization and de-initialization. However, there are other flows that are also using that same entry for their own purpose, and might run concurrently with the original flows [notice that for most cases using the main-ptt by mistake, such a race is still impossible, at least today]. This patch re-organizes the various functions that currently use the main_ptt in one of two ways: - If a function shouldn't use the main_ptt it starts acquiring and releasing it's own PTT entry and use it instead. Notice if those functions previously couldn't fail, they now can [as acquisition might fail]. - Change the prototypes so that the main_ptt would be received as a parameter [instead of explicitly accessing it]. This prevents the future risk of adding codes that introduces new use-cases for flows using the main_ptt, ones that might be in race with the actual 'main' flows.

When qedr is enabled, qed would try dividing the msi-x vectors between L2 and RoCE, starting with L2 and providing it with sufficient vectors for its queues. Problem is qed would also do that for storage partitions, and as those don't need queues it would lead qed to award those partitions with 0 msi-x vectors, causing them to believe theye're using INTa and preventing them from operating.

2017-03-28qed: Utilize resource-lock based schemeTomer Tayar6-166/+468
Management firmware is used as an arbiter between the various PFs in matters of resources, but some of the resources that need to be divided are dependent on the non-management firmware used, so management firmware first needs to be told how many resources there are before trying to divide them. As part of the initialization sequence, driver would first inform the management firmware of the available resources under a dedicated resource lock, and afterwards request for various resources which might be based on the previous set values.

2017-03-28qed: Support management-based resource lockingTomer Tayar3-0/+269
Global locking can't properly be used to synchronize between different PFs in all scenarios, as those instances might reside in different logical partitions [e.g., when a PF is assigned via PDA to some VM]. The management firmware provides a generic infrastructure for device locks. For each 'resource', it's guaranteed it could be acquired by at most a single PF at any given time [or by management firmware]. This patch adds the necessary logic in qed for utilizing said infrastructure, implementing lock/unlock internal APIs.

2017-03-28qed: Send pf-flr as part of initializationMintz, Yuval4-0/+28
During HW initialization, driver would set various registers to their needed values - but it assumes all registers start at their reset-value, so there's no need to re-configure a register's default value. This assumption might be incorrect, e.g., in case of preboot driver running and initializing the driver prior to our driver. To overcome this, we now ask management firmware to initiate a PF-flr early during the initialization sequence. That would return everything in the PF's scope back to default and prevent previous configurations from still being applied. Signed-off-by: Yuval Mintz <[email protected]> Signed-off-by: David S.
