Use the existing %pad printk format to print dma_addr_t values.
This avoids the following warnings when compiling on the parisc platform:
warning: format '%llx' expects argument of type 'long long unsigned int', but
argument 2 has type 'dma_addr_t {aka unsigned int}' [-Wformat=]

On XDP_TX we need to free up the frame only when tun_xdp_tx() returns a
negative value. A positive value indicates that the packet is
successfully enqueued to the ptr_ring, so freeing the page causes
use-after-free.

Once mtu_set_by_user is set to true, br_mtu_auto_adjust will
not run, and no chance to clear mtu_set_by_user.
and br_mtu_auto_adjust will run only if mtu_set_by_user is
false, so not need to set it to false again
