Hostapd uses 'crc32' name for IEEE802.11 CRC-32 routine. This name is too generic. Buildroot autobuilder detected configurations that failed to build due to the naming conflict with zlib-ng. Add hostapd part of the upstream patch that renames 'crc32' function to a less generic 'ieee80211_crc32' name.

Subject: [PATCH] hostapd: use a less generic name for IEEE802.11 CRC-32 routine
|
|
|
|
Hostapd uses 'crc32' name for IEEE802.11 CRC-32 routine. This name is
|
|
too generic. Buildroot autobuilder detected build configuration that
|
|
failed to build due to the naming conflict: static linking with openssl
|
|
using zlib-ng as a zlib provider, e.g. see:
|
|
- http://autobuild.buildroot.net/results/9901df820d3afa4cde78e8ad6d62cb8ce7e69fdb/
|
|
- http://autobuild.buildroot.net/results/ac19975f0bf77f4a8ca574c374092ba81cd5a332/
|
|
|
|
Use a less generic name ieee80211_crc32 for IEEE802.11 CRC-32 routine
|
|
to avoid such naming conflicts.
