[PATCH net-next 0/5] net/mlx5e: improve RSS indirection table sizing and resizing

[Tariq Toukan <tariqt@nvidia.com>]

Hi,

This series by Yael improves mlx5e RSS indirection table handling around
channel count changes and large RSS configurations.

The series:
* removes the XOR8-specific channel count limitation,
* advertises the maximum supported RSS indirection table size,
* fixes resizing of non-default RSS contexts,
* allows resizing configured default RSS contexts during channel
  changes,
* and increases the default RSS spread factor from 2x to 4x to improve
  traffic distribution for large channel counts.

Together, these changes make RSS table sizing more flexible and robust,
while improving load balancing behavior on large systems.

Thanks,
Tariq
