New buffers with different RX ring count should\nsubstitute older ones, but those buffers were freed in ice_vsi_cfg_rxq\nand reallocated again with ice_alloc_rx_buf. kfree on rx_buf caused\nleak of already mapped DMA.\nReallocate ZC with xdp_buf struct, when BPF program loads. Reallocate\nback to rx_buf, when BPF program unloads.\nIf BPF program is loaded/unloaded and XSK pools are created, reallocate\nRX queues accordingly in XDP_SETUP_XSK_POOL handler.\n\nSteps for reproduction:\nwhile :\ndo\n\tfor ((i=0; i<=8160; i=i+32))\n\tdo\n\t\tethtool -G enp130s0f0 rx $i tx $i\n\t\tsleep 0.5\n\t\tethtool -g enp130s0f0\n\tdone\ndone"
