netmap: silence -Wdefault-const-init-field-unsafe warning

2025-12-16T20:21:45Z

The netmap_ring struct starts with various const members and rencent clang warns about leaving them uninitialized. Having them const in the first place is highly suspicious since they are updated with various macros but using hand-coded __DECONST(). But fixing that is a more invasive change that I am unable to test. ``` .../freebsd/sys/dev/netmap/netmap_kloop.c:320:21: error: default initialization of an object of type 'struct netmap_ring' with const member leaves the object uninitialized [-Werror,-Wdefault-const-init-field-unsafe] 320 | struct netmap_ring shadow_ring; /* shadow copy of the netmap_ring */ | ^ .../freebsd/sys/net/netmap.h:290:16: note: member 'buf_ofs' declared 'const' here 290 | const int64_t buf_ofs; | ^ ``` Test Plan: Compiles Reviewed by: vmaffione, jhb MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D52568

netmap: Let memory allocator parameters be settable via loader.conf

2025-12-14T15:47:48Z

This is useful when dev.netmap.port_numa_affinity is set to 1. When interfaces attach, they get a memory allocator that is copied from nm_mem. Parameters in nm_mem can be set using sysctls, but this happens after their values are copied. To work around this, we can make it possible to set these memory parameters as tunables.

netmap: Fix error handling in nm_os_extmem_create()

2025-10-17T12:55:17Z

We bump the object reference count prior to mapping it into the kernel map, at which point the vm_map_entry owns the reference. Then, if vm_map_wire() fails, vm_map_remove() will release the reference, so we should avoid decrementing it in the error path.

vtnet, ptnet: include opt_*.h files early

2025-08-21T15:18:07Z

Include opt_inet.h and opt_inet6.h early in the files including virtio_net.h, since they use INET and/or INET6. While there, remove redundant inclusion of sys/types.h, since it is included already by sys/param.h. There was a discussion to include opt_inet.h and opt_inet6.h also in virtio_net.h. glebius suggested to add a mechanism for files to check, if required opt_*.h files were included. virtio_net.h will be the first consumer of this mechanism.
