2019-11-08ice: delay lessMitch Williams1-2/+3
Shorten the delay for SQ responses, but increase the number of loops. Max delay time is unchanged, but some operations complete much more quickly. In the process, add a new define to make the delay count and delay time more explicit. Add comments to make things more explicit. This fixes a problem with VF resets failing on with many VFs.

2019-05-30ice: Trivial cosmetic changesAnirudh Venkataramanan1-1/+1
This patch mostly capitalizes abbreviations in code comments. Fixed some typos and removed some unnecessary newlines as well.

2019-05-04ice: Use more efficient structuresJesse Brandeburg1-2/+2
Move a bunch of members around to make more efficient use of memory, eliminating holes where possible. None of these members are hot path so cache line alignment is not very important here.

2018-10-24ice: Update expected FW versionAnirudh Venkataramanan1-3/+2
Update to the current firmware major and minor version which are 1 and 3 respectively. Also remove an empty comment line.

2018-10-03ice: Add support to detect SR-IOV capability and mailbox queuesAnirudh Venkataramanan1-0/+2
Mailbox queue is a type of control queue that's used for communication between PF and VF. This patch adds code to initialize, configure and use mailbox queues. This patch also adds support to detect and parse SR-IOV capabilities returned by the hardware.

2018-03-26ice: Initialize PF and setup miscellaneous interruptAnirudh Venkataramanan1-0/+8
This patch continues the initialization flow as follows: 1) Allocate and initialize necessary fields (like vsi, num_alloc_vsi, irq_tracker, etc) in the ice_pf instance. 2) Setup the miscellaneous interrupt handler. This also known as the "other interrupt causes" (OIC) handler and is used to handle non hotpath interrupts (like control queue events, link events, exceptions, etc. 3) Implement a background task to process admin queue receive (ARQ) events received by the driver.

2018-03-26ice: Start hardware initializationAnirudh Venkataramanan1-0/+3
This patch implements multiple pieces of the initialization flow as follows: 1) A reset is issued to ensure a clean device state, followed by initialization of admin queue interface. 2) Once the admin queue interface is up, clear the PF config and transition the device to non-PXE mode. 3) Get the NVM configuration stored in the device's non-volatile memory (NVM) using ice_init_nvm.

2018-03-26ice: Add support for control queuesAnirudh Venkataramanan1-0/+83
A control queue is a hardware interface which is used by the driver to interact with other subsystems (like firmware, PHY, etc.). It is implemented as a producer-consumer ring. More specifically, an "admin queue" is a type of control queue used to interact with the firmware. This patch introduces data structures and functions to initialize and teardown control/admin queues. Once the admin queue is initialized, the driver uses it to get the firmware version.
