2020-02-26net/smc: improve peer ID in CLC decline for SMC-RHans Wippel
According to RFC 7609, all CLC messages contain a peer ID that consists of a unique instance ID and the MAC address of one of the host's RoCE devices. But if a SMC-R connection cannot be established, e.g., because no matching pnet table entry is found, the current implementation uses a zero value in the CLC decline message although the host's peer ID is set to a proper value. If no RoCE and no ISM device is usable for a connection, there is no LGR and the LGR check in smc_clc_send_decline() prevents that the peer ID is copied into the CLC decline message for both SMC-D and SMC-R. So, this patch modifies the check to also accept the case of no LGR. Also, only a valid peer ID is copied into the decline message. Signed-off-by: Hans Wippel <ndev@hwipl.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2018-10-24iov_iter: Separate type from direction and use accessor functionsDavid Howells
In the iov_iter struct, separate the iterator type from the iterator direction and use accessor functions to access them in most places. Convert a bunch of places to use switch-statements to access them rather then chains of bitwise-AND statements. This makes it easier to add further iterator types. Also, this can be more efficient as to implement a switch of small contiguous integers, the compiler can use ~50% fewer compare instructions than it has to use bitwise-and instructions. Further, cease passing the iterator type into the iterator setup function. The iterator function can set that itself. Only the direction is required.

SMC code uses the base gid for VLAN traffic. The gids exchanged in the CLC handshake and the gid index used for the QP have to switch from the base gid to the appropriate vlan gid.
