From 82a4e71b1565dea8387f54503e806cf374e779ec Mon Sep 17 00:00:00 2001 From: Sudarsana Reddy Kalluru Date: Sun, 1 Jul 2018 20:03:08 -0700 Subject: qede: Adverstise software timestamp caps when PHC is not available. When ptp clock is not available for a PF (e.g., higher PFs in NPAR mode), get-tsinfo() callback should return the software timestamp capabilities instead of returning the error.
