Many users of PCI config read routines tend to ignore the function
ret value, and are only concerned about the contents of *val. Based
on this, pci_hose_read_config_{byte,word}_via_dword should initialize
the *val on dword read error.
Without this fix, for example, we'll go on scanning bus with vendor or
header_type uninitialized. This brings many unnecessary config trials.

Don't wait for disconnected TSECs
The TSEC driver's PHY code waits a long time for autonegotiation to
complete, even if the link is down. The PHY knows the link is
down or up before autonegotiation completes, so we can short-circuit
the process if the link is down.

Define tsec flag values in config files
The tsec_info structure and array has a "flags" field for each

Instead of always using the largest blocksize the card supports, check
