Commit 46d3ceab "tcp: TCP Small Queues" has severly degraded performance for single connection RR workloads on HiperSockets with MTU >=16K due to a conflict of the TCP Small Queues approach with our buffer scan threshold which releases buffers not frequently enough yet.

As of now, s390dbf entries for the cards are discarded as soon as the device is removed.

The existing port isolation mode 'forward' will now verify that the adjacent switch port supports the required reflective relay (RR) mode. This patch adds the required error handling for the cases where enabling port isolation mode 'forward' can now fail. Furthermore, once established, we never fall back from one of the port isolation modes to a non-isolated mode without further user-interaction. This includes cases where the isolation mode was enabled successfully, but ceases to work e.g. due to configuration changes at the switch port. Finally, configuring an isolation mode with the device being offline will make onlining the device fail permanently upon errors encountered until either errors are resolved or the isolation mode is changed by the user to a different mode.

Change return code handling of the stsi() function: In case function code 0 was specified the return value is the current configuration level (already shifted). That way all the code that actually copied the stsi_0() function can go away. Otherwise the return value is 0 (success) or negative to indicate an error (currently only -EOPNOTSUPP). Also stsi() is no longer an inline function. The function is not performance critical, but every caller would generate an exception table entry for this function.

We did have a lot of sightly different statements and wanted to change them one after another whenever a file gets touched. However that never happened. Instead people start to take the old/"wrong" statements to use as a template for new files. So unify all of them in one go. Signed-off-by: NHeiko Carstens <heiko.carstens@de.ibm.com>

This patch extends the HiperSockets device driver to send and receive af_iucv traffic over HiperSockets transport. TX: Driver uses new asynchronous delivery of storage blocks to pass flow control/congestion information from the HiperSockets microcode to the af_iucv socket. RX: Memory for incoming traffic is preallocated and passed to HiperSockets layer. If receiver is not capable to clean its buffers shared with HiperSockets and pass new memory to the HiperSockets layer this will cause flow control/congestion events on the sender.
