Broadcom's 575xx adapter series has support for SRIOV VFs. Making changes
to enable SRIOV VF support. There are two major area where changes are
done:
- Added new DB location for control-path and data-path DB ring
- New devices do not need to issue the sriov-config slow-path command
thus, skipping to call that firmware command.
For now enabling support for 64 RoCE VFs.

The default maximum immediate size is too big for old srp clients, which
do not support immediate data.
According to the SRP and SRP-2 specifications, the IOControllerProfile
attributes for SRP target ports contains the maximum initiator to target
iu length.
The maximum initiator to target iu length can be obtained by sending MAD
packets to query subnet manager port and SRP target ports. We should
calculate the max_it_iu_size instead of the default value, when remote
maximum initiator to target iu length available.

According to SRP specifications 'srp-r16a' and 'srp2r06',
IOControllerProfile attributes for SRP target port include the maximum
initiator to target IU size.
SRP connection daemons, such as srp_daemon, can get the value from the
subnet manager. The SRP connection daemon can pass this value to kernel.
This patch adds a parse function for it.
Upstream commit [1] enables the kernel parameter, 'use_imm_data', by
default. [1] also use (8 * 1024) as the default value for kernel parameter
'max_imm_data'. With those default values, the maximum initiator to target
IU size will be 8260.
In case the SRPT modules, which include the in-tree 'ib_srpt.ko' module,
do not support SRP-2 'immediate data' feature, the default maximum
initiator to target IU size is significantly smaller than 8260. For
'ib_srpt.ko' module, which built from source before [2], the default
maximum initiator to target IU is 2116.
[1] introduces a regression issue for old srp targets with default kernel
parameters, as the connection will be rejected because of a too large
maximum initiator to target IU size.

Here are 2 small Documentation/process/embargoed-hardware-issues.rst
file updates that missed my previous char/misc pull request for 5.4-rc1.
The first one adds an Intel representative for the process, and the
second one cleans up the text a bit more when it comes to how the
disclosure rules work, as it was a bit confusing to some companies.

Additional fixes from last week to better handle some newly discovered

more atomically (in SMB3 Create security descriptor context), and one
for path name processing are still being tested so are not included
