commit bd877e48 ("net: qmi_wwan: use a single bind function for all device types") made Gobi 1K devices fail probing. Using the number of endpoints in the default altsetting to decide whether the function use one or two interfaces is wrong. Other altsettings may provide more endpoints. With Gobi 1K devices, USB interface #3's altsetting is 0 by default, but altsetting 0 only provides one interrupt endpoint and is not sufficent for QMI. Altsetting 1 provides all 3 endpoints required for qmi_wwan and works with QMI. Gobi 1K layout for intf#3 is: Interface Descriptor: 255/255/255 bInterfaceNumber 3 bAlternateSetting 0 Endpoint Descriptor: Interrupt IN Interface Descriptor: 255/255/255 bInterfaceNumber 3 bAlternateSetting 1 Endpoint Descriptor: Interrupt IN Endpoint Descriptor: Bulk IN Endpoint Descriptor: Bulk OUT Prior to commit bd877e48, we would call usbnet_get_endpoints before giving up finding enough endpoints. Removing the early endpoint number test and the strict functional descriptor requirement allow qmi_wwan_bind to continue until usbnet_get_endpoints has made the final attempt to collect endpoints. This restores the behaviour from before commit bd877e48 without losing the added benefit of using a single bind function. The driver has always required a CDC Union functional descriptor for two-interface functions. Using the existence of this descriptor to detect two-interface functions is the logically correct method.

When SCTP is done processing a duplicate cookie chunk, it tries to delete a newly created association. For that, it has to set the right association for the side-effect processing to work. However, when it uses the SCTP_CMD_NEW_ASOC command, that performs more work then really needed (like hashing the associationa and assigning it an id) and there is no point to do that only to delete the association as a next step. In fact, it also creates an impossible condition where an association may be found by the getsockopt() call, and that association is empty. This causes a crash in some sctp getsockopts. The solution is rather simple. We simply use SCTP_CMD_SET_ASOC command that doesn't have all the overhead and does exactly what we need.

Commit d13ba512 ("tg3: Remove SPEED_UNKNOWN checks") cleaned up the autoneg advertisement by removing some dead code. One effect of this change was that the advertisement register would not be updated if autoneg is turned off. This exposed a bug on the 5715 device w.r.t linking. The 5715 defaults to advertise only 10Mb Full duplex. But with autoneg disabled, it needs the configured speed enabled in the advertisement register to link up. This patch adds the work around to advertise all speeds on the 5715 when autoneg is disabled.

bond_update_speed_duplex() might sleep while calling underlying slave's routines. Move it out of atomic context in bond_enslave() and remove it from bond_miimon_commit() - it was introduced by commit 546add79, however when the slave interfaces go up/change state it's their responsibility to fire NETDEV_UP/NETDEV_CHANGE events so that bonding can properly update their speed. I've tested it on all combinations of ifup/ifdown, autoneg/speed/duplex changes, remote-controlled and local, on (not) MII-based cards. All changes are visible.

Commit fae50823 ("net: ethernet: davinci_cpdma: Add boundary for rx and tx descriptors") introduced a function to check the current allocation state of tx packets. The return value is taken into account to stop the netqork queue on the adapter in case there are no free slots. However, cpdma_check_free_tx_desc() returns 'true' if there is room in the bitmap, not 'false', so the usage of the function is wrong.

Using TX push when notifying the NIC of multiple new descriptors in the ring will very occasionally cause the TX DMA engine to re-use an old descriptor. This can result in a duplicated or partly duplicated packet (new headers with old data), or an IOMMU page fault. This does not happen when the pushed descriptor is the only one written. TX push also provides little latency benefit when a packet requires more than one descriptor. Signed-off-by: NBen Hutchings <bhutchings@solarflare.com>
