The main firmware messaging function returns the firmware defined error
code and many callers have to convert to standard error code for proper
propagation to userspace. Convert bnxt_hwrm_do_send_msg() to return
standard error code so we can do away with all the special error code
handling by the many callers.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct spider_net_card {
...
struct spider_net_descr darray[0];
};
Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes.
So, replace the following form:
sizeof(struct spider_net_card) + (tx_descriptors + rx_descriptors) * sizeof(struct spider_net_descr)
with:
struct_size(card, darray, tx_descriptors + rx_descriptors)
Notice that, in this case, variable alloc_size is not necessary, hence it
is removed.

Supported is EEE for 100Mbps and 1Gbps. Realtek recommended to not yet

of their tx queues among the different LAG ports.
2) Aya adds the support for ip-in-ip RSS.
3) Marina adds the support for ip-in-ip TX TSO and checksum offloads.

Add rules to the steering table regarding outer IP header, with
IPv4/6->IP-in-IP. Tunneled packets with protocol numbers: 0x4 (IP-in-IP)
and 0x29 (IPv6) are RSS-ed on the inner IP header.
Separate FW dependencies between flow table inner IP capabilities and
GRE offload support. Allowing this feature even if GRE offload is not
supported. Tested with multi stream TCP traffic tunneled with IPnIP.
Verified that:
Without this patch, only a single RX ring was processing the traffic.
With this patch, multiple RX rings were processing the traffic.
Verified with and without GRE offload support.

When the VF LAG is in use, round-robin the TX affinity of channels among
the different ports, if supported by the firmware. Create a set of TISes
per port, while doing round-robin of the channels over the different
sets. Let all SQs of a channel share the same set of TISes.
If lag_tx_port_affinity HCA cap bit is supported, num_lag_ports > 1 and
we aren't the LACP owner (PF in the regular use), assign the affinities,
otherwise use tx_affinity == 0 in TIS context to let the FW assign the
affinities itself. The TISes of the LACP owner are mapped only to the
native physical port.
For VFs, the starting port for round-robin is determined by its vhca_id,
because a VF may have only one channel if attached to a single-core VM.

Use different namespaces for bypass and switchdev loopback because they
have different priorities and default table miss action requirement:
1. bypass: with multiple priorities support, and
MLX5_FLOW_TABLE_MISS_ACTION_DEF as the default table miss action;
2. switchdev loopback: with single priority support, and
MLX5_FLOW_TABLE_MISS_ACTION_SWITCH_DOMAIN as the default table miss
action.

Currently all the namespaces under the same steering domain share the same

different actions are required. This patch adds a per-namespace default

This is because the implementation of refcount_t can prevent

The current loopback mode is to add 0x1F to the SMAC address
as the DMAC address and enable the promiscuous mode.
However, if the VF address is the same as the DMAC address,
the loopback test fails.
Loopback can be enabled in three places: SSU, MAC, and serdes.
By default, SSU loopback is enabled, so if the SMAC and the DMAC
are the same, the packets are looped back in the SSU. If SSU loopback
is disabled, packets can reach MAC even if SMAC is the same as DMAC.
Therefore, this patch disables the SSU loopback before the loopback
test. In this way, the SMAC and DMAC can be the same, and the
promiscuous mode does not need to be enabled. And this is not
valid in version 0x20.
This patch also uses a macro to replace 0x1F.
