The TSEC network interface driver is used on several Freescale SoC. I want to use it on the P1020RDB and MVME2500 (P2020) boards. I had problems with the MII communication. the transmit throughput and a deadlock in case of system overload.

if_tsec: Assume fixed link if no PHY is present
Thanks, for the commits. This patch is necessary for the P1020RDB.
I still have some performance problems, since for each transmit frame we do an M_PREPEND(m0, sizeof(struct tsec_tx_fcb), M_NOWAIT) for the checksum offload. I guess it would be more efficient to pre-allocate the FCB together with the descriptors. I am now busy with other projects and may resume this work in October 2017.

Shall we close this PR and you can submit a new PR or Phabricator review with future performance changes?

I will use a new PR or Phabricator review for follow up patches.
What is preferred PR or Phabricator review?
