NPAR (Network interface card partitioning)[1] 1.2 adds a transparent VLAN tag for all packets between the NIC and the switch. Because of that, RX VLAN acceleration cannot be supported for any additional host configured VLANs. The driver has to acknowledge that it can support no RX VLAN acceleration and set the NPAR 1.2 supported flag when registering with the FW. Otherwise, the FW call will fail and the driver will abort on these NPAR 1.2 NICs with this error: bnxt_en 0000:26:00.0 (unnamed net_device) (uninitialized): hwrm req_type 0x1d seq id 0xb error 0x2 [1] https://techdocs.broadcom.com/us/en/storage-and-ethernet-connectivity/ethernet-nic-controllers/bcm957xxx/adapters/introduction/features/network-partitioning-npar.html Reviewed-by: Somnath Kotur <somnath.kotur@broadcom.com> Reviewed-by: Michal Swiatkowski <michal.swiatkowski@linux.intel.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Link: https://patch.msgid.link/20250213011240.1640031-2-michael.chan@broadcom.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
