Host system running Scientific Linux 6.4, 2 5110p MICs with MPSS 2.1.6720-13.
Configured external bridge with MTU 1500 (our switches don't like anything bigger than that).
Each time we do micctrl --resetconfig or just reboot host system, both host's and mic's virtual mic0 interface is configured with MTU of 64k, which obviously doesn't work well when connected directly to bridge interface with MTU set to 1500. Even plain lsiting of files on NFS mount takes ages, transfers in few KB/s range.
Manual setting of MTU=1500 on host and in /opt/mic/filesystem/micX/etc/sysconfig/network/ifcfg-mic0, followed by service network restart and micctrl -R works as workaround, but i'm looking for more convenient and persistent solution.
Any ideas ?
