It is there. Checkout v2 of the series, an equivalent parameter was added: tx-offloads.

Since testpmd is now using the new Ethdev offloads API there is no

need for the txqflags configuration.



txqflag command-line option (--txqflags=0xXXXXXXXX) and command

(port

config all txqflags value) are way to dynamically provide Tx offload

configuration to testpmd.



Why you are removing them without providing equivalent feature with

new offload APIs?



There is one, and this is why the new offloads API simplifies applications

life.

The txq_flags were introduced so application can disable some of the Tx

offloads from the time the Tx offloads were set by default.



Now the Tx offloads are all disabled by default. And there is an option to

set each one of the using DEV_TX_OFFLOAD_* flags.

Look on the Rx side (there the Rx offloads were disabled by default in the

old API). there is no rxq_flags.



I mean providing a testpmd command and command-line option.

Or am I missing it, after this update is there a way to update enabled Tx

offloads in testpmd via command and command-line?



There is a way to update via CLI

For example when doing "tso set <mss> <port>" the DEV_TX_OFFLOAD_TSO will be set

When doing tx_vlan add <port> <vlan> the DEV_TX_OFFLOAD_VLAN_INSERT will be set

Same for every Tx offloads besides DEV_TX_OFFLOAD_MULTI_SEGS  and DEV_TX_OFFLOAD_MBUF_FAST_FREE which I added on separate patches.



But to make it precise you didn’t had before (with the txq_flags) a way to disable TSO from the command line (the is no TXQ flag for that) nor the tunnel TSO.









Patch 3/4 & 4/5 adds new command-line options to enable some of

recently introduced Tx offloads in testpmd, why not add a generic way

to update all Tx offloads instead of those two specific offloads?



Because those 2 new offloads were missing a way to set in testpmd.

The rest of the offloads can be set using the CLI commands exists today.



Am not sure we want every Tx offloads to be set from both CLI and

command line arguments.

It wasn't before (for example there was no --disable-tso flags).



I was thinking a generic command-line instead of introducing one for all,

overall single variable represents all offload values, why not set it at once, as

--txqflags you are removing in this patch.



We can do it. yes.

+1 for Ferruh. --txqflags argument was very handy in testing features in batch mode. Let us have something equivalent.













Also this patch removing ability to display current Tx offload

configuration....



Can you point where ?



I mean following:



  -       printf("  TX RS bit threshold=%d - TXQ flags=0x%"PRIx32"\n",

  -              tx_conf->tx_rs_thresh, tx_conf->txq_flags);

  +       printf("  TX RS bit threshold=%d\n", tx_conf->tx_rs_thresh);



Why not an offloads replacement of this one?



Will be added.
