2016-09-10net: vrf: Flip IPv6 output path from FIB lookup hook to out hookDavid Ahern
Flip the IPv6 output path to use the l3mdev tx out hook. The VRF dst is not returned on the first FIB lookup. Instead, the dst on the skb is switched at the beginning of the IPv6 output processing to send the packet to the VRF driver on xmit. Link scope addresses (linklocal and multicast) need special handling: specifically the oif the flow struct can not be changed because we want the lookup tied to the enslaved interface. ie., the source address and the returned route MUST point to the interface scope passed in.

2016-09-10net: fs_enet: make rx_copybreak value configurableChristophe Leroy
Measurement shows that on a MPC8xx running at 132MHz, the optimal limit is 112: * 114 bytes packets are processed in 147 TB ticks with higher copybreak * 114 bytes packets are processed in 148 TB ticks with lower copybreak * 128 bytes packets are processed in 154 TB ticks with higher copybreak * 128 bytes packets are processed in 148 TB ticks with lower copybreak * 238 bytes packets are processed in 172 TB ticks with higher copybreak * 238 bytes packets are processed in 148 TB ticks with lower copybreak However it might be different on other processors and/or frequencies.

2016-09-10net: fs_enet: don't unmap DMA when packet len is below copybreakChristophe Leroy
When the length of the packet is below the defined copybreak limit, the received packet is copied into a newly allocated skb in order to reuse the skb. This is only interesting if it allow us to avoid a new DMA mapping. We shall therefore not DMA unmap and remap the skb->data. Instead, we invalidate the cache with dma_sync_single_for_cpu() once the received data has been copied into the new skb. The following measures have been obtained on a mpc885 running at 132Mhz. Measurement is done using the timebase with packets sent to the target with 'ping -s 1' (packet len is 60): * Without this patch: 182 TB ticks * With this patch: 143 TB ticks As a comparison, if we set the copybreak limit to 0, then we get 148 TB ticks. It means that without this patch, duration is even worse when copying received data to a new skb instead of allocating a new skb for next packet to be received Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-09-10net: fs_enet: merge NAPI RX and NAPI TXChristophe Leroy
Initially, a NAPI TX routine has been implemented separately from NAPI RX, as done on the freescale/gianfar driver. By merging NAPI RX and NAPI TX, we reduce the amount of TX completion interrupts. Handling of the budget in association with TX interrupts is based on indications provided at https://wiki.linuxfoundation.org/networking/napi We never proceed more than the complete TX ring on a single run. At the same time, we fix an issue in the handling of fep->tx_free: It is only when fep->tx_free goes up to MAX_SKB_FRAGS that we need to wake up the queue. There is no need to call netif_wake_queue() at every packet successfully transmitted. Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-09-10net: ethernet: renesas: sh_eth: add POST registers for rzChris Brandt
Due to a mistake in the hardware manual, the FWSLC and POST1-4 registers were not documented and left out of the driver for RZ/A making the CAM feature non-operational. Additionally, when the offset values for POST1-4 are left blank, the driver attempts to set them using an offset of 0xFFFF which can cause a memory corruption or panic. This patch fixes the panic and properly enables CAM.
