[dpdk-dev] [PATCH v3 1/3] lib/librte_table: add hash_func header files

[dpdk-dev] [PATCH v3 1/3] lib/librte_table: add hash_func header files

[Kevin Laatz]

This commit adds rte_table_hash_func.h and rte_table_hash_func_arm64.h to
librte_table. This reduces code duplication by removing duplicate header files
within two folders and consolidating them into a single one. This also adds a
scalar implementation of the x86_64 intrinsic for crc32 as a generic fallback.

v2:
   - Fixed typo in commit message
   - Fixed typo in arm header that caused some compilations to fail for the
     entire patchset
v3:
   - Improved commit message

[dpdk-dev] [PATCH v3 2/3] examples/ip_pipeline: modify application to use librte_table headers

[Kevin Laatz]

This commit modifies the IP Pipeline application to use the new header
files in librte_table.

As we are now using the new header files, we can remove the old ones from
the application directory.

[dpdk-dev] [PATCH v3 3/3] net/softnic: modify softnic to use librte_table headers

[Kevin Laatz]

This commit modifies SoftNIC to make use of the new header files in
librte_table.

As we are now using the new header files in librte_table in SoftNIC, we no
longer need the old header files so they can be removed.

ARM specific change and this patchset looks good. But, It has following

Wrong headline format:
	lib/librte_table: add hash_func header files
	examples/ip_pipeline: modify application to use librte_table
headers
	net/softnic: modify softnic to use librte_table headers
Headline too long:
	examples/ip_pipeline: modify application to use librte_table
headers
Line too long:
	librte_table. This reduces code duplication by removing
duplicate header files
	within two folders and consolidating them into a single one.
This also adds a
	scalar implementation of the x86_64 intrinsic for crc32 as a
generic fallback.

Thanks, Jerin, this looks like a map file issue, we'll work to fix it.

[dpdk-dev] [PATCH v4 1/3] lib/librte_table: add hash func header files

[Kevin Laatz]

This commit adds rte_table_hash_func.h and rte_table_hash_func_arm64.h to
librte_table. This reduces code duplication by removing duplicate header
files within two folders and consolidating them into a single one. This
also adds a scalar implementation of the x86_64 intrinsic for crc32 as a
generic fallback.

[dpdk-dev] [PATCH v4 2/3] examples/ip_pipeline: modify to use new table lib headers

[Kevin Laatz]

This commit modifies the IP Pipeline application to use the new header
files in librte_table.

As we are now using the new header files, we can remove the old ones from
the application directory.

[dpdk-dev] [PATCH v4 3/3] net/softnic: modify to use new table lib headers

[Kevin Laatz]

This commit modifies SoftNIC to make use of the new header files in
librte_table.

As we are now using the new header files in librte_table in SoftNIC, we no
longer need the old header files so they can be removed.
