Grow sc_nrxfqs from 1 to the CPU total, and hash the RX 5-tuple across the range with the KG driver from the prior commit. Each FQ lands on its own per-CPU QMan channel, so a given core drains only its own share of RX work and gets frame annotation + data-head stashed into its cache. * Add alignment parameter to qman_alloc_fqid_range() to meet KeyGen requirements. * Initialize 1 frame queue (FQ) per CPU in dpaa_eth_fm_port_rx_init(), using a 5-tuple to spread the load across CPUs. * Channel ownership for TX confirms moved from rx_init/free to tx_init/free -- sc_rx_channel is now a TX-confirm-only per-port pool channel. Fallbacks/degradation: * If any per-CPU channel is -1 (no portal attached) the port fails to attach with a clear message. * If the FQID range can't be allocated aligned, the port fails attach. * If KG scheme allocation fails at port setup, the port keeps its N FQs but only FQ #0 sees traffic.
