Hi Gagandeep,

Since the patchset has been sent after RC1, I assume it is for 19.08. Can you
please mark patch title as 19.08 to not confuse with current release?

Thanks,

[dpdk-dev] [PATCH 13/13] net/enetc: fix crash at high speed traffic

[Gagandeep Singh]

On xmit side, there should be a check whether BD ring
has free BDs available before transmit a packet to avoid
data corruption and buffer leak issue.

Fixes: 469c6111a799 ("net/enetc: enable Rx and Tx")

[dpdk-dev] [PATCH v2 13/13] net/enetc: fix crash at high speed traffic

[Gagandeep Singh]

On xmit side, there should be a check whether BD ring
has free BDs available before transmit a packet to avoid
data corruption and buffer leak issue.

[dpdk-dev] [PATCH v3 03/13] net/enetc: fix big endian build and correct buffer allocation

[Gagandeep Singh]

There was an error at rte_constant_bswap64 while compiling
with big endian toolchain. so fixing it by adding type cast.

Also, rte_pktmbuf_alloc API should be used to allocate mbuf
instead of rte_pktmbuf_raw_alloc to avoid use of stale mbuf
information.

[dpdk-dev] [PATCH v3 13/13] net/enetc: fix crash at high speed traffic

[Gagandeep Singh]

On xmit side, there should be a check whether BD ring
has free BDs available before transmit a packet to avoid
data corruption and buffer leak issue.

[dpdk-dev] [PATCH v4 03/13] net/enetc: fix big endian build and correct buffer allocation

[Gagandeep Singh]

There was an error at rte_constant_bswap64 while compiling
with big endian toolchain. so fixing it by adding type cast.

Also, rte_pktmbuf_alloc API should be used to allocate mbuf
instead of rte_pktmbuf_raw_alloc to avoid use of stale mbuf
information.

[dpdk-dev] [PATCH v4 13/13] net/enetc: fix crash at high speed traffic

[Gagandeep Singh]

On xmit side, there should be a check whether BD ring
has free BDs available before transmit a packet to avoid
data corruption and buffer leak issue.

Hi Gagandeep,

Can you please send a release notes update to document the update in the PMD, I
can squash into the patchset if it comes in time.

Hi Ferruh,

Yes, it was my mistake I was little late while pushing patches. Actually these patches are for 19.05 release.
If it not bother you, could you please merge these patches to 19.05? otherwise I'll mark title to 19.08.
