New Revision: 308319
URL: https://svnweb.freebsd.org/changeset/base/308319

Log:
  MFC 297875: cxgbe(4): Always read the entire mailbox into the reply buffer.
  
  The size of the reply can be different from the size of the command in
  case a debug firmware asserts.  fw_asrt() needs the entire reply in
  order to decode the location of the assert.
