2016-07-09ibmvnic: Fix passive VNIC server login processThomas Falcon
In some cases, if there is no VNIC server available during the driver probe, the driver should wait until it receives an initialization request from the VNIC Server to start the login process. Recent testing has show that this is incorrectly handled in the current driver. The proposed solution handles this initialization request by scheduling a task in the shared workqueue that completes the login process and registers the net device.

2016-07-09ibmvnic: simplify and improve driver probe functionThomas Falcon
This patch creates a function that handles sub-CRQ IRQ creation separately from sub-CRQ initialization. Another function is then needed to release sub-CRQ resources prior to sub-CRQ IRQ creation. These additions allow the driver probe function to be simplified, specifically during the VNIC Server login process. A timeout is also included while waiting for completion of the login process in case the VNIC Server is not available or some other error occurs.

2016-04-09ibmvnic: Enable use of multiple tx/rx scrqsJohn Allen
Enables the use of multiple transmit and receive scrqs allowing the ibmvnic driver to take advantage of multiqueue functionality. To achieve this, the driver must implement the process of negotiating the maximum number of queues allowed by the server. Initially, the driver will attempt to login with the maximum number of tx and rx queues supported by the server. If the server fails to allocate the requested number of scrqs, it will return partial success in the login response. In this case, we must reinitiate the login process from the request capabilities stage and attempt to login requesting fewer scrqs.

A new function is included for the hypervisor call, H_SEND_SUBCRQ_INDIRECT, allowing a DMA-mapped array of SCRQ descriptor elements to be sent to the VNIC server.

2015-12-15net: Rename NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASKTom Herbert
The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the set of features for offloading all checksums. This is a mask of the checksum offload related features bits. It is incorrect to set both NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for features of a device. This patch: - Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where NETIF_F_ALL_CSUM is being used as a mask). - Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to use NEITF_F_HW_CSUM in features list instead of NETIF_F_ALL_CSUM.

The size of the MAC register dump used to be the size specified by the reg property in the device tree. Userland has no good way of finding out that size, and it was not specified consistently for each MAC type, so ethtool would end up printing junk at the end of the register dump if the device tree didn't match the size it assumed. Using the new version numbers indicates unambiguously that the size of the MAC register dump is dependent only on the MAC type.

2015-06-23drivers/net: remove all references to obsolete Ethernet-HOWTOPaul Gortmaker
This howto made sense in the 1990s when users had to manually configure ISA cards with jumpers or vendor utilities, but with the implementation of PCI it became increasingly less and less relevant, to the point where it has been well over a decade since I last updated it. And there is no value in anyone else taking over updating it either. However the references to it continue to spread as boiler plate text from one Kconfig file into the next. We are not doing end users any favours by pointing them at this old document, so lets kill it with fire, once and for all, to hopefully stop any further spread.

2015-04-25ehea: Fix memory hook reference counting crashesMichael Ellerman
The recent commit to only register the EHEA memory hotplug hooks on adapter probe has a few problems. Firstly the reference counting is wrong for multiple adapters, in that the hooks are registered multiple times. Secondly the check in the tear down path is backward. Finally the error path doesn't decrement the count. The multiple registration of the hooks is the biggest problem, as it leads to oopses when the system is rebooted, and/or errors during memory hotplug, eg: $ ./mem-on-off-test.sh -r 2 ... ehea: memory is going offline ehea: LPAR memory changed - re-initializing driver ehea: re-initializing driver complete ehea: memory is going offline ehea: LPAR memory changed - re-initializing driver ehea: opcode=26c ret=fffffffffffffffc arg1=8000000003000003 arg2=0 arg3=700000060000d600 arg4=3fded0000 arg5=200 arg6=0 arg7=0 ehea: register_rpage_mr failed ehea: registering mr failed ehea: register MR failed - driver inoperable! ehea: memory is going offline Fixes: aa183323312d ("ehea: Register memory hotplug, reboot and crash hooks on adapter probe") Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: David S.

2015-04-23ibmveth: Fix off-by-one error in ibmveth_change_mtu()David Gibson
AFAIK the PAPR document which defines the virtual device interface used by the ibmveth driver doesn't specify a specific maximum MTU. So, in the ibmveth driver, the maximum allowed MTU is determined by the maximum allocated buffer size of 64k (corresponding to one page in the common case) minus the per-buffer overhead IBMVETH_BUFF_OH (which has value 22 for 14 bytes of ethernet header, plus 8 bytes for an opaque handle). This suggests a maximum allowable MTU of 65514 bytes, but in fact the driver only permits a maximum MTU of 65513. This is because there is a < instead of an <= in ibmveth_change_mtu(), which only permits an MTU which is strictly smaller than the buffer size, rather than allowing the buffer to be completely filled. This patch fixes the buglet. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Acked-by: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Conflicts: drivers/net/ethernet/emulex/benet/be_main.c net/core/sysctl_net_core.c net/ipv4/inet_diag.c The be_main.c conflict resolution was really tricky. The conflict hunks generated by GIT were very unhelpful, to say the least.

This makes it possible to push traffic to this driver that has TSO or partial checksums set, but also have a non-accelearted vlan header. In this case, the driver will fail to correctly identify such traffic and will not correctly perform segmentation and checksum calculation.
