The generic param max_macs documentation isn't clear.
Replace it with a more descriptive documentation

Add new device generic parameter to determine the size of the
asynchronous control events EQ.
For example, to reduce event EQ size to 64, execute:
$ devlink dev param set pci/0000:06:00.0 \
name event_eq_size value 64 cmode driverinit
$ devlink dev reload pci/0000:06:00.0

Add new device generic parameter to enable/disable creation of
VDPA net auxiliary device and associated device functionality
in the devlink instance.
User who prefers to disable such functionality can disable it using below
example.
$ devlink dev param set pci/0000:06:00.0 \
name enable_vnet value false cmode driverinit
$ devlink dev reload pci/0000:06:00.0
At this point devlink instance do not create auxiliary device for the
VDPA net functionality.

The enable_remote_dev_reset devlink param flags that the host admin
allows device resets that can be initiated by other hosts. This
parameter is useful for setups where a device is shared by different
hosts, such as multi-host setup. Once the user set this parameter to
false, the driver should NACK any attempt to reset the device while the
driver is loaded.

We are having multiple review cycles with all vendors trying
to implement devlink-info. Let's expand the documentation with
more information about what's implemented and motivation behind
this interface in an attempt to make the implementations easier.
Describe what each info section is supposed to contain, and make
some references to other HW interfaces (PCI caps).
Document how firmware management is expected to look, to make
it clear how devlink-info and devlink-flash work in concert.
Name some future work.
v2: - improve wording
v3: - improve wording
