    SubjectRe: [PATCH 2/2] dp83640: increase receive time stamp buffer size
    From: Richard Cochran <>
    Date: Sun, 7 Aug 2011 09:03:04 +0200

    > The dp83640 buffers receive time stamps from special PHY status frames,
    > matching them to received PTP packets in a work queue. Because the timeout
    > for orphaned time stamps is so long and the buffer is so small, the driver
    > can drop time stamps under moderate PTP traffic.
    > This commit fixes the issue by decreasing the timeout to (at least) one
    > timer tick and increasing the buffer size.
