net: ipa: simplify TX completion statistics
When a TX request is issued, its channel's accumulated byte and transaction counts are recorded. This currently does *not* take into account the transaction being committed. Later, when the transaction completes, the number of bytes and transactions that have completed since the transaction was committed are reported to the network stack. The transaction and its byte count are accounted for at that time. Instead, record the transaction and its bytes in the counts recorded at commit time. This avoids the need to do so when the transaction completes, and provides a (small) simplification of that code. Signed-off-by: Alex Elder <elder@linaro.org> Signed-off-by: David S.
