    Please dont copy code you dont understand :(

    bridge code is ok, but not yours, since you destroy the kmem_cache when
    a net namespace exits.

    Either you fix your code, either you change your memory allocations to
    mere kmalloc()/kfree() calls and dont care of a private kmem_cache you
    have to create and destroy.

    Since you ask a SLAB_HWCACHE_ALIGN, the SLUB allocator will anyway merge
    your kmem_cache with the standard one (kmalloc-64 I guess)
