irqbalance: upgrade to 1.6.0
Upgraded from 1.2.0 to 1.6.0 to pick up all the latest fixes and improvements irqbalance made glib2 mandatory since 1.3.0, but is using very little of it. glib2 linked statically to minimize the impact. 1.2.0 size: 33,619 1.6.0 size: 99,539 ~# irqbalance --version irqbalance version 1.6.0 ~# ldd /usr/sbin/irqbalance /lib/ld-musl-armhf.so.1 (0xb6f5f000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0xb6f43000) libc.so => /lib/ld-musl-armhf.so.1 (0xb6f5f000) ~# opkg info irqbalance Package: irqbalance Version: 1.6.0-6 Depends: libc Status: install user installed Architecture: arm_cortex-a7_neon-vfpv4 Installed-Time: 1582839249 Compile-tested: ipq806x/R7800 & ipq40xx/GL-B1300 Run-tested: ipq806x/R7800 & ipq40xx/GL-B1300 Signed-off-by: Marc Benoit <marcb62185@gmail.com>lilik-openwrt-22.03
