In case of ->set_param() and ->bind_conn() cxgb4i driver does not wait for cmd completion, this can create race conditions, to avoid this add wait_for_completion(). Signed-off-by: Varun Prakash <varun@chelsio.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

The same effects can be achieved by setting the dma_boundary to PAGE_SIZE - 1 and the max_segment_size to PAGE_SIZE, so shift those settings into the drivers.

2018-11-21scsi: cxgb4i: fix thermal configuration dependenciesArnd Bergmann1-2/+2
I fixed a bug by adding a dependency in the network driver, but that fix caused a related bug in the SCSI driver: WARNING: unmet direct dependencies detected for CHELSIO_T4 Depends on [m]: NETDEVICES [=y] && ETHERNET [=y] && NET_VENDOR_CHELSIO [=y] && PCI [=y] && (IPV6 [=y] || IPV6 [=y]=n) && (THERMAL [=m] || !THERMAL [=m]) Selected by [y]: - SCSI_CXGB4_ISCSI [=y] && SCSI_LOWLEVEL [=y] && SCSI [=y] && PCI [=y] && INET [=y] && (IPV6 [=y] || IPV6 [=y]=n) drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_init': cxgb4_thermal.c:(.text+0x158): undefined reference to `thermal_zone_device_register' drivers/net/ethernet/chelsio/cxgb4/cxgb4_thermal.o: In function `cxgb4_thermal_remove': cxgb4_thermal.c:(.text+0x1d8): undefined reference to `thermal_zone_device_unregister' /git/arm-soc/Makefile:1042: recipe for target 'vmlinux' failed The same dependency needs to be propagated here to make it work correctly with CONFIG_THERMAL=m and SCSI_CXGB4_ISCSI=y. That change by itself causes another problem with a circular dependency, as we use 'select NETDEVICES'. This is something we really should not do anyway, as a driver symbol should never select another major subsystem, so let's turn that into a 'depends on'. I don't see any downsides of that, as NETDEVICES is only disabled in rather obscure cases that are not relevant to the users of cxgb4i.
