[PATCH v2 net 6/6] selftests: drv-net: add xdp cases for ping.py

ping.py has 3 cases, test_v4, test_v6 and test_tcp. But these cases are not executed on the XDP environment. So, it adds XDP environment, existing tests(test_v4, test_v6, and test_tcp) are executed too on the below XDP environment. So, it adds XDP cases. 1. xdp-generic + single-buffer 2. xdp-generi

[PATCH v2 net 5/6] net: devmem: do not WARN conditionally after netdev_rx_queue_restart()

When devmem socket is closed, netdev_rx_queue_restart() is called to reset queue by the net_devmem_unbind_dmabuf(). But callback may return -ENETDOWN if the interface is down because queues are already freed when the interface is down so queue reset is not needed. So, it should not warn if the retu

[PATCH v2 net 4/6] eth: bnxt: do not update checksum in bnxt_xdp_build_skb()

The bnxt_rx_pkt() updates ip_summed value at the end if checksum offload is enabled. When the XDP-MB program is attached and it returns XDP_PASS, the bnxt_xdp_build_skb() is called to update skb_shared_info. The main purpose of bnxt_xdp_build_skb() is to update skb_shared_info, but it updates ip_su

[PATCH v2 net 1/6] eth: bnxt: fix truesize for mb-xdp-pass case

When mb-xdp is set and return is XDP_PASS, packet is converted from xdp_buff to sk_buff with xdp_update_skb_shared_info() in bnxt_xdp_build_skb(). bnxt_xdp_build_skb() passes incorrect truesize argument to xdp_update_skb_shared_info(). The truesize is calculated as BNXT_RX_PAGE_SIZE * sinfo->nr_fra

[PATCH v2 net 3/6] eth: bnxt: do not use BNXT_VNIC_NTUPLE unconditionally in queue restart logic

When a queue is restarted, it sets MRU to 0 for stopping packet flow. MRU variable is a member of vnic_info[], the first vnic_info is default and the second is ntuple. Only when ntuple is enabled(ethtool -K eth0 ntuple on), vnic_info for ntuple is allocated in init logic. The bp->nr_vnics indicates

[PATCH v2 net 2/6] eth: bnxt: return fail if interface is down in bnxt_queue_mem_alloc()

The bnxt_queue_mem_alloc() is called to allocate new queue memory when a queue is restarted. It internally accesses rx buffer descriptor corresponding to the index. The rx buffer descriptor is allocated and set when the interface is up and it's freed when the interface is down. So, if queue is rest

[PATCH v2 net 0/6] eth: bnxt: fix several bugs in the bnxt module

The first fixes setting incorrect skb->truesize. When xdp-mb prog returns XDP_PASS, skb is allocated and initialized. Currently, The truesize is calculated as BNXT_RX_PAGE_SIZE * sinfo->nr_frags, but sinfo->nr_frags is flushed by napi_build_skb(). So, it stores sinfo before calling napi_build_skb()
