Michal Jaron 3daf097819 iavf: Fix set max MTU size with port VLAN and jumbo frames
[ Upstream commit 399c98c4dc50b7eb7e9f24da7ffdda6f025676ef ]

After setting port VLAN and MTU to 9000 on VF with ice driver there
was an iavf error
"PF returned error -5 (IAVF_ERR_PARAM) to our request 6".

During queue configuration, VF's max packet size was set to
IAVF_MAX_RXBUFFER but on ice max frame size was smaller by VLAN_HLEN
due to making some space for port VLAN as VF is not aware whether it's
in a port VLAN. This mismatch in sizes caused ice to reject queue
configuration with ERR_PARAM error. Proper max_mtu is sent from ice PF
to VF with GET_VF_RESOURCES msg but VF does not look at this.

In iavf change max_frame from IAVF_MAX_RXBUFFER to max_mtu
received from pf with GET_VF_RESOURCES msg to make vf's
max_frame_size dependent from pf. Add check if received max_mtu is
not in eligible range then set it to IAVF_MAX_RXBUFFER.

Fixes: dab86afdbb ("i40e/i40evf: Change the way we limit the maximum frame size for Rx")

README

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 Restructured Text 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.
