bnxt_en: Add bp->rx_dir field for rx buffer DMA direction.
When driver is running in XDP mode, rx buffers are DMA mapped as DMA_BIDIRECTIONAL. Add a field so the code will map/unmap rx buffers according to this field. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

_mountpoint a function that does the hash table lookup and addition under the mount_lock. The introduction of get_mounptoint ensures that only the mount_lock is needed to manipulate the mountpoint hashtable. d_set_mounted is modified to only set DCACHE_MOUNTED if it is not already set. This allows get_mountpoint to use the setting of DCACHE_MOUNTED to ensure adding a struct mountpoint for a dentry happens exactly once.
