6d1ef2abd3 ena: Implement full RSS reconfiguration
Bind RX/TX queues and MSI-X vectors to matching CPUs based on the RSS
bucket entries.

Introduce sysctls for the following RSS functionality:
- rss.indir_table:      indirection table mapping
- rss.indir_table_size: indirection table size
- rss.key:              RSS hash key (if Toeplitz used)

Said sysctls are only available when compiled without `option RSS`, as
kernel-side RSS support currently doesn't offer RSS reconfiguration.

Migrate the hash algorithm from CRC32 to Toeplitz and change the initial
hash value to 0x0 in order to match the standard Toeplitz implementation.
Provide helpers for hash key inversion required for HW operations.

986e7b9227 ena: Move RSS logic into its own source files
Delegate RSS related functionality into separate .c/.h files in
preparation for the full RSS support.

While at it, reorder functions and remove prototypes for ones with
internal linkage.
