Hi Justin,

I believe that you also need:

select PAGE_POOL

As the driver uses page_pool_alloc_pages()

FWIIW, I observed this when using a config based on make tinyconfig with
PCI and NET enabled, all WiFi drivers disabled, and only and only this Ethernet
driver enabled.

The advice above to chose Y and M seem to conflict.
Perhaps this can be edited somehow.

Subject: RE: [PATCH net-next v17 12/13] realtek: Update the Makefile and Kconfig in the realtek folder

The problem this time seems to be caused by me not doing a rebase.
I will modify the reviewer's suggestions in the next version and re-upload
the next version after rebase.

Hi Simon,
I would like to ask if it would be clearer if I changed it to the following?

config RTASE
tristate "Realtek Automotive Switch 9054/9068/9072/9075/9068/9071 PCIe Interface support"
depends on PCI
select CRC32
select PAGE_POOL
help
Say Y here and it will be compiled and linked with the kernel
if you have a Realtek Ethernet adapter belonging to the
following families:
RTL9054 5GBit Ethernet
RTL9068 5GBit Ethernet
RTL9072 5GBit Ethernet
RTL9075 5GBit Ethernet
RTL9068 5GBit Ethernet
RTL9071 5GBit Ethernet

To compile this driver as a module, choose M here: the module
will be called rtase. This is recommended.

Thanks Justin,

Yes, I think that addresses my concern.
