Subject: sfc: split setup of hardware timestamping into NIC-type operation
X-Git-Tag: v3.14-rc1~94^2~493^2~7
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9ec0659595c8020f1efa55aa00870e8773f8ee89;p=pandora-kernel.git

sfc: split setup of hardware timestamping into NIC-type operation

I added efx_ptp_get_mode() to avoid moving the definition for
efx_ptp_data, since the current PTP mode is needed for
siena.c:siena_set_ptp_hwtstamp.

[bwh: Also move the rx_filters mask, and add kernel-doc]
