[dpdk-dev] [PATCH v2 0/5] fix bitmask of supported Tx flags

[Jingjing Wu]

Some Tx offload flags are missed in bitmask of all supported packet
Tx flags, it will cause rte_eth_tx_prepare fails when Tx burst packets.

v2 changes:
 - redefine the PKT_TX_OFFLOAD_MASK
 - fix more drivers

Jingjing Wu (5):
  mbuf: fix bitmask of Tx offload flags
  net/i40e: fix bitmask of supported Tx flags
  net/ixgbe: fix bitmask of supported Tx flags
  net/e1000: fix bitmask of supported Tx flags
  net/fm10k: fix bitmask of supported Tx flags

Functionally will be same, but what do you think about following, to
make easy to see what define adds:

Hi, Ferruh

As I know, the above change is incorrect in C code. We cannot use #ifdef  #endif inside #define

You can do:

#ifdef RTE_LIBRTE_IEEE1588
#define I40_TX_IEEE1588_TMST PKT_TX_IEEE1588_TMST
#else
#define I40_TX_IEEE1588_TMST 0
#endif

#define I40E_TX_OFFLOAD_MASK (   \
	I40_TX_IEEE1588_TMST |   \
	PKT_TX_IP_CKSUM |	 \
	...

Hi Jingjing,

Could you detail which flag was missing?
Is it PKT_TX_TUNNEL_MASK?
If yes, shouldn't we have a "Fixes:" line?

I think most of the patchset should be merged in one patch, because
changing only the mbuf part (PKT_TX_OFFLOAD_MASK) would break the
drivers that checks the offload bits at init, and this is not suitable,
especially if we want to be able to do git bisect.


My suggestion is to have:

1- fix i40 (add missing tunnel mask?)
2- fix missing MACSET in TX_OFFLOAD_MASK
3- change TX_OFFLOAD_MASK to include all flags (this impacts all
   drivers using TX_OFFLOAD_MASK)


Regards,
Olivier

Same question for e1000 and fm10k.
Also if you decided to go that way, you'll probably need to update TX_OFFLOAD_MASK
for enic and vmxnet3.
That's why I still think it would be much less hassle not to include
these flags (PKT_TX_IPV4 and PKT_TX_IPV6)  into TX_OFFLOAD_MASK at all.

Thanks for pointing that. PKT_TX_IPV6 is missed.
About whether include these flags (PKT_TX_IPV4 and PKT_TX_IPV6)  into TX_OFFLOAD_MASK, I think they should be
Included. Think about one NIC may support IPV4 L4 checksum offload, but not support IPV6? Even I don't know who it is.

I don't think such combination is possible now anyway.
But ok, if your preference is it to do more work and add (PKT_TX_IPV4 | PKT_TX_IPV6)
into all required places, I wouldn't argue.

BTW, as a side notice, what will be really good is to have a function that would take
tx_offload_capabilities as an input and return tx_offload_mask.
That would remove necessity to update/support TX_OFFLOAD_MASK for each PMD,
and hopefully will allow to avoid confusion for PMD writers. 
Though that's probably subject of another patch.

OK. I think what I did is more than necessary. Let me simplify the change. Thanks!

And about the querying tx offload capabilities, I think it is already been done
In rte_eth_dev_info_get. But it used another set of flags which is not TX flags
Defined in mbuf.

I am not talking about querying device offload capabilities.
I am talking about a function that would take these capabilities reported by the
device and convert them into a set of tx offload flags, that are suitable for these capabilities. 
Something like that:
uint64_t
tx_capa_to flags(uint32_t tx_capa)
{
	uint64_t ol_flags;
	
	ol_flags = 0;

	if (tx_capa &  DEV_TX_OFFLOAD_TCP_TSO)
		ol_flags |= PKT_TX_TCP_SEG |  PKT_TX_IPV4 |  PKT_TX_IP_CKSUM  | PKT_TX_IPV6;
	if (tx_capa &  DEV_TX_OFFLOAD_TCP_CKSUM)
		ol_flags |= PKT_TX_TCP_CKSUM;
	...
	return ol_flags;
}   

Then PMD writer wouldn't need to define TX_OFFLOAD_MASK for his PMD manually.
Instead he can just do at startup/configure phase:
txq->tx_offload_mask = tx_capa_to flags(supported_and_configured_capabilties);

Though, as I said, this is probably subject of another patch/discussion.

[dpdk-dev] [PATCH v3 1/4] net/i40e: fix bitmask of supported Tx flags

[Jingjing Wu]

PKT_TX_TUNNEL_MASK and PKT_TX_IEEE1588_TMST are missed in bitmask
of all supported packet Tx flags by i40e. It will cause packet preparing
fail when sending tunnel packets with Tx offload.
This patch fixes it.

PKT_TX_IEEE1588_TMST added into I40E_TX_OFFLOAD_MASK, but not into
PKT_TX_OFFLOAD_MASK (patch 4/4)

Shouldn't PKT_TX_OFFLOAD_MASK be a super set of driver ones. Otherwise
PKT_TX_IEEE1588_TMST will be marked as not supported according below XOR
logic.

Yes, you are right. Should I send a new version patch set? Or just update the [4/4]?

[dpdk-dev] [PATCH v4 1/4] net/i40e: fix bitmask of supported Tx flags

[Jingjing Wu]

PKT_TX_TUNNEL_MASK and PKT_TX_IEEE1588_TMST are missed in bitmask
of all supported packet Tx flags by i40e. It will cause packet preparing
fail when sending tunnel packets with Tx offload.
This patch fixes it.

Hi Jingjing,

Just to confirm, other drivers that use PKT_TX_OFFLOAD_MASK not updated
because they don't support newly added flags, right?
