    net: set SK_MEM_QUANTUM to 4096 · bd68a2a8

    Systems with large pages (64KB pages for example) do not always have
    huge quantity of memory.
    
    A big SK_MEM_QUANTUM value leads to fewer interactions with the
    global counters (like tcp_memory_allocated) but might trigger
    memory pressure much faster, giving suboptimal TCP performance
    since windows are lowered to ridiculous values.
    
    Note that sysctl_mem units being in pages and in ABI, we also need
    to change sk_prot_mem_limits() accordingly.
