Preparation for upcoming ethernet driver.
- Move msix array from eq_table struct to priv since its not related to eq_table
- Intorduce irq_info struct to hold all irq information
- Move name from mlx5_eq to irq_info struct since it is irq property.
- Set IRQ affinity hints

Would be nicer to use dev_to_node helper here, which already checks for
CONFIG_NUMA
include/linux/device.h:
#ifdef CONFIG_NUMA
static inline int dev_to_node(struct device *dev)
{
return dev->numa_node;
}
static inline void set_dev_node(struct device *dev, int node)
{
dev->numa_node = node;
}
#else
static inline int dev_to_node(struct device *dev)
{
return -1;
}
static inline void set_dev_node(struct device *dev, int node)
{
}
#endif

- Direct buf allocation will be allocated via mlx5_buf_alloc_direct.
- Add and export mlx5_buf_alloc_pages to be used by mlx5_buf_alloc as before.
- Add virtual_extension parameter to be used to request to virtually extended
buffer pages for cyclic usage, to avoid handling wqe wrap around the buffer.

I'm sorry but I'm going to require that you fix this mis-use of the DMA
API first.
You absolutely cannot vmap() pages backing coherent DMA memory, the
memory is mapped in a particular way by dma_*_coherent() and you must
therefore only use the virtual address provided to you by that
function to access the memory.

Curious ordering and numbering.
There's no 0xd or 0xe, 0x16, 0x17, 0x18, 0x1e
Are those reserved?

This structure has one use, but so far that seems
unused. Will this be used later?
Decimal is generally easier to read than hex.
The code is generally easier too if instead of an
array definition of size 1 it's a simple type.
If these are autogenerated, and length/position are important,
it could be nice to do something like:
struct <foo> {
type array1[decimal_size]; /* Hex offset */
...
}
[]

Why all the blank lines?
If this is autogenerated from a document with comments,
maybe the autogenerator could elide the blank lines too
when in a structure.

Yes, But since PRM keeps evolving we want to keep track the PRM

Yes. Unused values are reserved. And the ordering is the same like we

Yes. Those structures are being used through the macros MLX5_[GS]ET*

We decided to use hex values, since the PRM is written with hex values.

This entry actually describes one bit.

Our tables are accessed as dwords. We add blank line between every
dword in the PRM.

The autogenerator completely ignores comments.

- Introduce new Macros to access/dump stored caps (using eat.me auto generated data types).
- obsolete SW representation of dev caps (no need for SW copy for each cap).
- modify ib driver to use new Macros for checking Caps.
