From 9feb16ae0b2d5246e20a8dd9049441780e59c2a1 Mon Sep 17 00:00:00 2001 From: Prasad Kanneganti Date: Tue, 3 Jan 2017 11:27:33 -0800 Subject: [PATCH] liquidio: remove PTP support in 23XX adapters liquidio driver incorrectly indicates that PTP is supported in 23XX adapters; this patch fixes that. PTP is supported in 66XX and 68XX adapters, and the driver correctly indicates that.
