From: Miroslav Lichvar Date: Fri, 19 May 2017 15:52:35 +0000 (+0200) Subject: net: define receive timestamp filter for NTP X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b8210a9e4bea6354eccc5d8a50ecc21ea7486dc9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git net: define receive timestamp filter for NTP Add HWTSTAMP_FILTER_NTP_ALL to the hwtstamp_rx_filters enum for timestamping of NTP packets. There is currently only one driver (phyter) that could support it directly. CC: Richard Cochran CC: Willem de Bruijn Signed-off-by: Miroslav Lichvar Signed-off-by: David S.
