This reverts commit 70355602. As pointed out by Mark McLoughlin IP_PKTINFO cmsg data is one post-queueing user, so this optimization is not valid right now. Signed-off-by: David S. Miller <davem@davemloft.net>

It generally helps to handle those values in various places, using it might make the code more readable and gives room for other improvements. The IEEE standard talks about them as "parameter values". Signed-off-by: Holger Eitzenberger <holger@eitzenberger.org> Signed-off-by: David S. Miller <davem@davemloft.net>

The patch which fixed gianfar so it drops packets when it runs out of memory left in the code which frees the skb when it drops packets.

In each case, if the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T; expression E; identifier i,fld; statement S; @@ - T i = E->fld; + T i; ... when != E when != i if (E == NULL) S + i = E->fld; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

genphy_setup_forced hasn't actually reset the PHY for a long time, but a comment to that effect remained in the code, so code continued to act as if it *had* reset the PHY, and called the necessary fixup functions to respond to a PHY reset. With no reset, those functions are no longer needed, so we remove them. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Whenever we want to update the status field in a BD, we usually want to update the length field, too. By combining them into one 32-bit field, we reduce the number of stores to memory shared with the controller, and we eliminate the need for order-enforcement, as the length and "READY" bit are now updated atomically at the same time.

This code is based strongly on code from Dai Haruki <Dai.Haruki@freescale.com>. The gianfar Buffer Descriptors are arranged in a circular array, the end of which is denoted by setting the "WRAP" bit in the descriptor. However, the software knows the end of the ring because it knows how many descriptors are there. Rather than check each descriptor for whether the WRAP bit is set, use pointer math to determine where the next BD is. This is also useful for when we want to look at BDs other than the very next one (for Scatter-Gather). Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: David S.

The eTSEC can prepend up to 32 bytes to a received frame, usually for the purpose of aligning the IP address to a word boundary, so this turns it on. While we're in there, make the handling of the pre-frame bytes (padding and Frame Control Block) cleaner.

Store the interrupt coalescing values in the form in which they will be written to the interrupt coalescing registers.

Does the same for the accompanying MDIO driver, and then modifies the TBI configuration method. The old way used fields in einfo, which no longer exists. The new way is to create an MDIO device-tree node for each instance of gianfar, and create a tbi-handle property to associate ethernet controllers with the TBI PHYs they are connected to.
