|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Yuval Mintz says: ==================== bnx2x: new features patch series This patch series adds/fixes several new features in the bnx2x driver - it adds support for loading the bnx2x over an UNDI running on a Multi-function device, adds missing bits for PCIe AER support and enables VFs to properly configure multicast filters (In addition, it also contains some small improvements in driver behaviour). Please consider applying these patches to `net-next'.

| * bnx2x: no error when RSS configuration failsYuval Mintz2013-12-261-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It's possible for VMs with older versions of bnx2x to run over a hypervisor with latest driver. If a VF in such a VM does not support RSS configuration, the PF driver in the hypervisor will print an error message to system logs. This changes the error message into a debug message, as this is very likely a false alarm for an older VF (i.e., VF manages to work properly; PF simply cannot configure the additional queues for it).

| * bnx2x: add Big-Endian ethtool commentYuval Mintz2013-12-261-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There's a known issue that using `ethtool -e' flips the endianity of the written data, i.e., using `ethtool -E' to dump eeprom image and than using `ethtool -e' to re-write that same image will result in an image where the data has the opposite endianity. Sadly, this cannot be fixed as there are already various tools deployed based on the endianity of the eeprom read/write. Instead, a comment is added to the code to help explain why this is un-fixable.

| * bnx2x: Add support for Multi-Function UNDIYuval Mintz2013-12-264-12/+87
|/ | | | | | | | | | | | | This adds the ability for bnx2x to load after UNDI is used in the preboot environment on a multi-function interface which is not the first interface of a given device. Notice a side-effect is that the order by which the functions are probed and thus interfaces appear might change, as this patch utilizes the EPROBE_DEFER return value (and mechanism).

If CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set, this uses the slightly faster generic routine ether_addr_equal, otherwise this uses memcmp. So I use the recently added and possibly more efficient ether_addr_equal_unaligned to instead of memcmp for slight optimization. v2: Because a lot of places are already using 16b aligned MAC address for both operands, so use the ether_addr_equal to instead of ether_addr_equal_unaligned.Thanks for Joe, Alex and Antonio's opinions. Also remove the patch for bridge. v3: According Joe's suggestion, the patch (net: slight optimization of addr compare for some modules) should be broken into several patches, and it will be good to review for maintainers. So I will send rest of the patches for first step, and next step, I will seperate the netdev patch and send them by another patchset for net-next. also fix some changelog. v3.5 Change some style for patch 8 and patch 13.

* net: vxlan: use custom ndo_change_mtu handlerDaniel Borkmann2013-12-231-1/+24
| | | | | | | | | | | | | | | | | | | | | | | When adding a new vxlan device to an "underlying carrier" (here: dst->remote_ifindex), the MTU size assigned to the vxlan device is the MTU at setup time of the carrier - needed headroom, when adding a vxlan device w/o explicit carrier, then it defaults to 1500. In case of an explicit carrier that supports jumbo frames, we currently cannot change vxlan MTU via ip(8) to > 1500 in post-setup time, as vxlan driver uses eth_change_mtu() as default method for manually setting MTU. Hence, use a custom implementation that only falls back to eth_change_mtu() in case we didn't use a dev parameter on device setup time, and otherwise allow a max MTU setting of the carrier incl. adjustment for headroom.
