Add additional logic to reserve completion rings for the bnxt_re driver
when it requests MSIX vectors. The function bnxt_cp_rings_in_use()
will return the total number of completion rings used by both drivers
that need to be reserved. If the network interface in up, we will
close and open the NIC
Currently, the driver code makes some assumptions about the group index
and the map index of rings. This makes the code more difficult to
understand and less flexible.
Improve it by adding the grp_idx and map_idx fields explicitly to the
bnxt_ring_struct as a union. The grp_idx is initialized fo
When checking for the maximum pre-set TX channels for ethtool -l, we
need to check the current max_tx_scheduler_inputs parameter from firmware.
This parameter specifies the max input for the internal QoS nodes currently
available to this function. The function's TX rings will be capped by this
par
Refactor bnxt_need_reserve_rings() slightly so that __bnxt_reserve_rings()
can call it and remove some duplicated code.

Add remapping logic so that bnxt_en can use any arbitrary MSIX vectors.
This will allow the driver to reserve one range of MSIX vectors to be
used by both bnxt_en and bnxt_re. bnxt_en can now skip over the MSIX
vectors used by bnxt_re.

Change the default ring logic to select default number of rings to be up to
8 per port if the default rings x NIC ports <= total CPUs.

When VFs are created, the current code subtracts the maximum VF
resources from the PF's pool. This under-estimates the resources
remaining in the PF pool. Instead, we should subtract the minimum
VF resources. The VF minimum resources are guaranteed to the VFs
and only these should be subtracted
When the driver needs to re-initailize the IRQ vectors, we make the
new ulp_irq_stop() call to tell the RDMA driver to disable and free
the IRQ vectors. After IRQ vectors have been re-initailized, we
make the ulp_irq_restart() call to tell the RDMA driver that
IRQs can be restarted.

Hi Joe
This does not look good.

Thanks everyone for reviewing the series.
Dave, this should apply clean on net-next tree and I think it is ready
to merge.
Series for Chelsio Inline TLS driver (chtls)
Use tls ULP infrastructure to register chtls as Inline TLS driver.
Chtls use TCP Sockets to Tx/Rx TLS records.
TCP sk_proto APIs
Initialize the space reserved for storing the TLS keys,
get and free the location where key is stored for the TLS
connection.
Program the Tx and Rx key as received from user in
struct tls12_crypto_info_aes_gcm_128 and understood by hardware.
added socket option TLS_RX
