session: allow small pacer bursts
Instead of enforcing a "strict" release of data, which relies on frequent rescheduling of sessions, allow some pacer coalescing, i.e., short bursts, that can minimize load on scheduler/session layer and potentially leverage tso. Type: improvement Signed-off-by: Florin Coras <fcoras@cisco.com> Change-Id: I67e38e5b8dc335bd214113b70c68c27ae92bd6da
