That speed supports signaling rate of 100Gb. mlx5 IB driver translates link modes reported by ConnectX device to IB speed and width. Added translation of new 100Gb, 200Gb and 400Gb link modes to NDR IB type and width of x1, x2 or x4 respectively.

Releasing items from the cache is a sleepable operation due to the need to await a response from the firmware command freeing the tag, so items cannot be reclaimed from the zone in non-sleepable contexts. Since the cache size is limited by firmware limits, avoid this by setting UMA_ZONE_UNMANAGED to avoid reclamation by uma_timeout() and the low memory handler.

This way import and release are guaranteed to process all allocated and then deallocated items. Also, the release occurs in a sleepable context when caller of uma_zfree() or uma_zdestroy() can sleep itself.

Then it is no longer needed to wait for refcounts to reach zero when destroying RX- and TX- TLS send tags as a result of pending data or WQE commands. This also ensures that when TX-TLS and rate limiting is used at the same time, the underlying SQ is not prematurely destroyed.
