[PATCH net-next v4 0/7] enic: Use all the resources configured on VIC

[Nelson Escobar <neescoba@cisco.com>]

Allow users to configure and use more than 8 rx queues and 8 tx queues
on the Cisco VIC.

This series changes the maximum number of tx and rx queues supported
from 8 to the hardware limit of 256, and allocates memory based on the
number of resources configured on the VIC.

Changes in v4:
- Followed Vadim Fedorenko's suggestions for re-arranging enic_wq and
  adding ____cacheline_aligned to the new structs.
- Link to v3: https://lore.kernel.org/r/20241108-remove_vic_resource_limits-v3-0-3ba8123bcffc@cisco.com

Changes in v3:
- Per Jakub's suggestions, split commit 5 into smaller commits and use
  net_get_num_default_rss_queues() to set the number of RQs used.
- Fixed an issue with commit 2 caught during testing with a missing
  changed needed in enic_init_vnic_resources().
- Link to v2: https://lore.kernel.org/r/20241024-remove_vic_resource_limits-v2-0-039b8cae5fdd@cisco.com
