* enic: rename CMD_MAC_ADDR to CMD_GET_MAC_ADDRRoopa Prabhu2012-02-204-6/+6
| | | | | | | | | | firmware devcmd CMD_MAC_ADDR gets the mac address of a vnic from adapter. This patch renames it to CMD_GET_MAC_ADDR more appropriately.

| | | | | | | | | | | | | | | Adapt adi ethernet driver to changes in bfin_get_ether_addr() from arch/blackfin. bfin_get_ether_addr() returns now a state. Set a random mac address via new eth_hw_addr_random() in case the return value is not 0. Reset the state to NET_ADDR_PERM as soon as the MAC get changed via .ndo_set_mac_address. v2: change the logic to reduce unneeded checks Signed-off-by: Danny Kukawka <danny.kukawka@bisect.de> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the MAC HW initialization and the HW feature verification from the open to the probe function as D. Miller suggested. So the patch actually reorganizes and tidies-up some parts of the driver and indeed fixes some problem when tune its HW features. These can be overwritten by looking at the HW cap register at run-time and that generated problems.

These may be assigned to up to 127 SR-IOV virtual functions per port, with up to 64 VIs per VF. We allocate an extra channel (IRQ and event queue only) to receive requests from VF drivers. There is a per-port limit of 4 concurrent RX queue flushes, and queue flushes may be initiated by the MC in response to a Function Level Reset (FLR) of a VF. Therefore, when SR-IOV is in use, we submit all flush requests via the MC. The RSS indirection table is shared with VFs, so the number of RX queues used in the PF is limited to the number of VIs per VF.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Abstract some of the channel operations to allow for 'extra' channels that do not have RX or TX queues. - Try to assign a channel to each extra channel type that is enabled for the NIC, but gracefully degrade if we can't allocate sufficient MSI-X vectors - Allow each extra channel type to generate its own channel name - Allow channel types to disable reallocation and reinitialisation of their channels Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The TX DMA engine issues upstream read requests when there is room in the TX FIFO for the completion. However, the fetches for the rest of the packet might be delayed by any back pressure. Since a flush must wait for an EOP, the entire flush may be delayed by back pressure. Mitigate this by disabling flow control before the flushes are started. Since PF and VF flushes run in parallel introduce fc_disable, a reference count of the number of flushes outstanding. The same principle could be applied to Falcon, but that would bring with it its own testing. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
