Dev pointer in airoha_ppe_foe_entry_prepare routine is not strictly
a device allocated by airoha_eth driver since it is an egress device
and the flowtable can contain even wlan, pppoe or vlan devices. E.g:
flowtable ft {
hook ingress priority filter
devices = { eth1, lan1, lan2, lan3, lan4, wlan0 }
flags offload ^
|
"not allocated by airoha_eth" --
}
In this case airoha_get_dsa_port() will just return the original device
pointer and we can't assume netdev priv pointer points to an
airoha_gdm_port struct.
Fix the issue validating egress gdm port in airoha_ppe_foe_entry_prepare
routine before accessing net_device priv pointer.

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.
