91721c2d02d3a0141df8a4787c7079b89b0d0607 Author: Daniel Xu Date: Fri Jul 21 14:22:46 2023 -0600 netfilter: bpf: Support BPF_F_NETFILTER_IP_DEFRAG in netfilter link This commit adds support for enabling IP defrag using pre-existing netfilter defrag support. Basically all the flag does is bump a refcnt while the link the active. Checks are also added to ensure the prog requesting defrag support is run _after_ netfilter defrag hooks. We also take care to avoid any issues w.r.t. module unloading -- while defrag is active on a link, the module is prevented from unloading.
