Dave Ertman de37510ec6 ice: Allow all LLDP packets from PF to Tx
[ Upstream commit f9f83202b7263ac371d616d6894a2c9ed79158ef ]

Currently in the ice driver, the check whether to
allow a LLDP packet to egress the interface from the
PF_VSI is being based on the SKB's priority field.
It checks to see if the packets priority is equal to
TC_PRIO_CONTROL.  Injected LLDP packets do not always
meet this condition.

SCAPY defaults to a sk_buff->protocol value of ETH_P_ALL
(0x0003) and does not set the priority field.  There will
be other injection methods (even ones used by end users)
that will not correctly configure the socket so that
SKB fields are correctly populated.

Then ethernet header has to have to correct value for
the protocol though.

Add a check to also allow packets whose ethhdr->h_proto
matches ETH_P_LLDP (0x88CC).

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.
