Logan Gunthorpe 980c41c86b NTB: Ensure ntb_mw_get_align() is only called when the link is up ... With Switchtec hardware it's impossible to get the alignment parameters for a peer's memory window until the peer's driver has configured its windows. Strictly speaking, the link doesn't have to be up for this, but the link being up is the only way the client can tell that the other side has been configured. This patch converts ntb_transport and ntb_perf to use this function after the link goes up. This simplifies these clients slightly because they no longer have to store the alignment parameters. It also tweaks ntb_tool so that peer_mw_trans will print zero if it is run before the link goes up.
