Subject: realtek: need to handle PHY_INTERFACE_MODE_NA for sfps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
From the validate docs in include/linux/phylink.h:
When state->interface is PHY_INTERFACE_MODE_NA, phylink expects the
MAC driver to return all supported link modes.
Tested-by: Birger Koblitz <mail@birger-koblitz.de>
Signed-off-by: Bjørn Mork <bjorn@mork.no>
(cherry picked from commit 785d830e889ba18793acf369e447d704269169af)
