Previously, EQ joined the chain notifier on creation. This forced the caller to be ready to handle events before creating the EQ through eq_create_generic interface. To help the caller control when the created EQ will be attached to the IRQ, add enable/disable API.

The patch modifies the IRQ allocation so that all async EQs are assigned to the same IRQ resulting in more available IRQs for completion EQs. The changes are using the support for IRQ sharing and EQ polling budget that was introduced in previous patches so when the shared interrupt is triggered, the kernel will serially call the handler of each of the sharing EQs with a certain budget of EQEs to poll in order to prevent starvation.

Multiple EQs may share the same IRQ in subsequent patches. Instead of calling the IRQ handler directly, the EQ will register to an atomic chain notfier. The Linux built-in shared IRQ is not used because it forces the caller to disable the IRQ and clear affinity before free_irq() can be called. This patch is the first step in the separation of IRQ and EQ logic.

Multiple EQs may share the same irq in subsequent patches. To avoid starvation, a budget is set per EQ's interrupt handler. Because of this change, it is no longer required to check that MLX5_NUM_SPARE_EQE eqes were polled (to detect that arm is required). It is guaranteed that MLX5_NUM_SPARE_EQE > budget, therefore the handler will arm and exit the handler before all the entries in the eq are polled. In the scenario where the handler is out of budget and there are more EQEs to poll, arming the EQ guarantees that the HW will send another interrupt and the handler will be called again.

For ECPF with eswitch manager privilege, query the host max VF count by querying the device using query_functions command. With this enhancement: 1. flow steering entries are created only for valid vports based on the max VF count of the PF. 2. Driver only queries cap of valid vport. Eswitch requires the max VFs when doing initialization, so do sr-iov init before eswitch init.

Currently for every representor type and for every single vport, representer function pointers copy is stored even though they don't change from one to other vport. Additionally priv data entry for the rep is not passed during registration, but its copied. It is used (set and cleared) by the user of the reps. As we want to scale vports, to simplify and also to split constants from data, 1. Rename mlx5_eswitch_rep_if to mlx5_eswitch_rep_ops as to match _ops prefix with other standard netdev, ibdev ops. 2. Constify the IB and Ethernet rep ops structure. 3. Instead of storing copy of all rep function pointers, store copy per eswitch rep type. 4. Split data and function pointers to mlx5_eswitch_rep_ops and mlx5_eswitch_rep_data.
