Revert "gnu: ucx: Update to 1.17.0."
This reverts commit 7c36577cde, which
broke unit tests running in the chroot build environment.
For instance, tests of ‘hdf5-parallel-openmpi’ would fail with:
Testing ../../src/h5diff/ph5diff -c 1_vds.h5 2_vds.h5 *FAILED*

Since /sys is unavailable in build environments, the list of available
|
||||
TCP network interfaces cannot be obtained via /sys/class/net. This patch
|
||||
provides alternative code that uses the SIOCGIFCONF ioctl to get the
|
||||
names of the available TCP network interfaces.
|
||||
|
||||
