New Revision: 330946
URL: https://svnweb.freebsd.org/changeset/base/330946
Log:
Remove TLS-related inlines from t4_tom.h to fix iw_cxgbe(4) build.
- Remove the one use of is_tls_offload() and the function. AIO special
handling only needs to be disabled when a TOE socket is actively doing
TLS offload on transmit. The TOE socket's mode (which affects receive
operation) doesn't matter, so remove the check for the socket's mode and
only check if a TOE socket has TLS transmit keys configured to determine
if an AIO write request should fall back to the normal socket handling
instead of the TOE fast path.
- Move can_tls_offload() into t4_tls.c. It is not used in critical paths,
so inlining isn't that important. Change return type to bool while here.
