Bug description:
Currently the maximum size of SMB2/3 header is set incorrectly which
leads to hanging of directory listing operations on encrypted SMB3
connections. Fix this by setting the maximum size to 170 bytes that
is calculated as RFC1002 length field size (4) + transform header
size (52) + SMB2 header size (64) + create response size (56).

next.git/commit/?id=47690ab81f4f29b12bbb0676d3579e61ab4d84de
This applies across the board 3.16, 4.4, 4.10, artful, and azure.
Microsoft would be happy to help test.
