From ea5ceeabf5621ed36d24e6741b45cfd1e1fce11b Mon Sep 17 00:00:00 2001 From: Tushar Dave Date: Fri, 14 Sep 2012 03:43:43 +0000 Subject: igb: Correcting and improving small packet check and padding Current implementation mess up the tail pointer. This patch sets skb->tail correctly. Also, the small packet check and padding is optimized by using unlikely and calling skb_pad directly.

The idea is to reduce partial cache line writes by hardware when handling frames larger then header size. We can compensate for the extra overhead of having to memcpy the header buffer by avoiding the cache misses seen by leaving an full skb allocated and sitting on the ring.

To resolve these locking issues I have moved the two function calls into __igb_open so that they can be called while the RTNL lock is held. An added advantage to this is that the number of queues is not updated until the last possible moment so if there are any issues in allocating MSI-X interrupts or resources for the rings we have time to change the values prior to updating the netdev.

Therefore: - Make PTP clock drivers select rather than depending on PTP_1588_CLOCK - Remove separate boolean options for PTP clock drivers that are built as part of net driver modules. (This also fixes cases where the PTP subsystem is wrongly forced to be built-in.) - Set 'default y' for PTP clock drivers that depend on specific net drivers but are built separately Signed-off-by: Ben Hutchings Signed-off-by: David S.
