2013-10-17dpaa_eth: Add pool channel in each affined portal's SDQCRCristian Sovaiala
There might be CPUs which are not enabled at boottime, therefore the pool channel is not currently set to the SDQCR of the affined portals of those CPUs. This means that the portals affined to the offline CPUs and which are migrated to the boot CPU, will not issue interrupts to the boot CPU in first instance and to the affined CPU (when this comes online) in the second instance. Therefore we set the pool channel to the SDQCR of each affined portal.

2013-10-01dpaa_eth: Replace for_each_online_cpu with for_each_possible_cpuCristian Sovaiala
At bootime, we currently initialize a NAPI instance per each online core, per interface. Booting with a subset of cores and bringing up more cores afterwards means that no NAPI instances are created for the newly added cores. Therefore we create a NAPI instance for each possible core in the system such that there will always be <total_no_of_cores> NAPI instances for each interface. This also gurantees that we do enable/disable NAPI on all possible cores at ifconfig up/down thus eliminating the need to keep track of the cores that were online at the previous ifconfig operation. Even though we do create a NAPI instance and enable it for all possible cores (including offline cores), the scheduler ensures that NAPI will not be scheduled on offline cores.

2013-09-10dpaa_eth: Remove dpa_bp pointer from percpu private structureIoana Radulescu
The reference to the buffer pool can be just as easily obtained from the netdev private structure, so do that and reduce the size of the percpu private struct.

2013-09-10dpaa_eth: Fix draining of buffer poolsIoana Radulescu
When draining buffers in batches of eight, we must take into account the fact that BMan will return an error code if there are less than eight buffers left in the pool; when this happens, drain the remaining buffers one by one. And since we're at buffer pool cleanup, make sure allocated bpools get freed in case of errors inside the probe function.
