Subject: [PATCH] -Retry get channel authentication capabilities command
 without the IPMI 2.0 bit  if the first one receives '0xCC'.  The x336 BMC,
 for one, checks the values  of the 'reserved' bits instead of ignoring them.

git-svn-id: https://svn.code.sf.net/p/xcat/code/xcat-core/trunk@2188 8638fb3e-16cb-4fca-ae20-7b5d299a9bcd
