Removing linux/phy.h from net/dsa.h reveals a build error in the sunrpc
code:

net/sunrpc/xprtrdma/svc_rdma_backchannel.c: In function 'xprt_rdma_bc_put':
net/sunrpc/xprtrdma/svc_rdma_backchannel.c:277:2: error: implicit declaration of function 'module_put' [-Werror=implicit-function-declaration]
net/sunrpc/xprtrdma/svc_rdma_backchannel.c: In function 'xprt_setup_rdma_bc':
net/sunrpc/xprtrdma/svc_rdma_backchannel.c:348:7: error: implicit declaration of function 'try_module_get' [-Werror=implicit-function-declaration]

Fix this by adding linux/module.h to svc_rdma_backchannel.c
