Subject: net: fec: access ->pp through netmem_desc instead of page
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=65589e860a803695da508e24c0ef2beaaaaa564b;p=thirdparty%2Flinux.git

net: fec: access ->pp through netmem_desc instead of page

To eliminate the use of struct page in page pool, the page pool users
should use netmem descriptor and APIs instead.

Make fec access ->pp through netmem_desc instead of page.
