2013-03-17drivers:net: dma_alloc_coherent: use __GFP_ZERO instead of memset(, 0)Joe Perches
Reduce the number of calls required to alloc a zeroed block of memory. Trivially reduces overall object size. Other changes around these removals o Neaten call argument alignment o Remove an unnecessary OOM message after dma_alloc_coherent failure o Remove unnecessary gfp_t stack variable Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

2013-03-17vxlan: generalize forwarding tablesDavid Stevens
This patch generalizes VXLAN forwarding table entries allowing an administrator to: 1) specify multiple destinations for a given MAC 2) specify alternate vni's in the VXLAN header 3) specify alternate destination UDP ports 4) use multicast MAC addresses as fdb lookup keys 5) specify multicast destinations 6) specify the outgoing interface for forwarded packets The combination allows configuration of more complex topologies using VXLAN encapsulation. Changes since v1: rebase to 3.9.0-rc2 Signed-Off-By: David L Stevens <dlstevens@us.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-03-17caif: remove caif_shmErwan Yvin
caif_shm is an old implementation caif_shm will be replaced by caif_virtio [ As explained by Linus Walleij: "U5500 used this, but was cancelled and the silicon did not reach anyone outside ST-Ericsson. Then for the next platforms, we have gone for the leaner & cleaner approach of using virtio, rpmesg and rproc." ] Signed-off-by: Erwan Yvin <erwan.yvin@stericsson.com> Acked-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Sjur Brendeland <sjur.brandeland@stericsson.com> Signed-off-by: David S.

2013-03-15drivers:net: Remove dma_alloc_coherent OOM messagesJoe Perches
I believe these error messages are already logged on allocation failure by warn_alloc_failed and so get a dump_stack on OOM. Remove the unnecessary additional error logging. Around these deletions: o Alignment neatening. o Remove unnecessary casts of dma_alloc_coherent. o Hoist assigns from ifs. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

2013-03-15netxen: write IP address to firmware when using bondingnikolay@redhat.com
This patch allows LRO aggregation on bonded devices that contain an NX3031 device. It also adds a for_each_netdev_in_bond_rcu(bond, slave) macro which executes for each slave that has bond as master. V3: After testing and discussing this with Rajesh, I decided to keep the vlan ip cache and just rename it to ip_cache since it will store bond ip addresses too. A new master flag has been added to the ip cache to denote that the address has been added because of a master device. I've taken care of the enslave/release cases by checking for various combinations of events and flags (e.g. netxen has a master, it's a bond master and it's not marked as a slave means it is being enslaved and is dev_open()ed in bond_enslave). I've changed netxen_free_ip_list() to have a "master" parameter which causes all IP addresses marked as master to be deleted (used when a netxen is being released). I've made the patch use the new upper device API as well. The following cases were tested: - bond -> netxen - vlan -> netxen - vlan -> bond -> netxen V2: Remove local ip caching, retrieve addresses dynamically and restore them if necessary. Note: Tested with NX3031 adapter.

2013-03-14RDMA/cxgb4: Fix onchip queue support for T5Vipul Pandya
T5 adapter does not support onchip queue memory. Present logic fails to allocate QP for T5 and returns an error. Also, if module parameter ocqp_support is zero then we are unable to allocate QP which should not be the case. Ideally if ocqp_support parameter is 0 or onchip queue support is disable then host QP should be allocated before returning an error.

2013-03-14RDMA/cxgb4: Use DSGLs for fastreg and adapter memory writes for T5.Vipul Pandya
It enables direct DMA by HW to memory region PBL arrays and fast register PBL arrays from host memory, vs the T4 way of passing these arrays in the WR itself. The result is lower latency for memory registration, and larger PBL array support for fast register operations. This patch also updates ULP_TX_MEM_WRITE command fields for T5. Ordering bit of ULP_TX_MEM_WRITE is at bit position 22 in T5 and at 23 in T4. Signed-off-by: Vipul Pandya <vipul@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

This has been tested on a qnap TS-119P II. Note that enabling WOL with "ethtool -s eth0 wol g" is not enough; you also need to tell the PIC microcontroller inside the qnap that WOL should be enabled by sending 0xF2 with qcontrol(1) and you have to disable EUP ("Energy-using Products", a European power-saving thing) by sending 0xF4.
