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.

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

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.
