Subject: NFC: llcp: Do not send pending Tx frames when the remote is not ready
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=2635a4bdfa8d513c531fa7d7a0ccafc1d6a9ff85;p=openwrt%2Fstaging%2Fblogic.git

NFC: llcp: Do not send pending Tx frames when the remote is not ready

When we receive a RNR, the remote is busy processing the last received
frame. We set a local flag for that, and we should send a SYMM when it
is set instead of sending any pending frame.
