Subject: [hermon] Throttle debug output when sensing port type
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7b2b35981f862ba17765c87f657353f93b5b41d4;p=thirdparty%2Fipxe.git

[hermon] Throttle debug output when sensing port type

When auto-detecting the initial port type, the Hermon driver will spam
the debug output without hesitation.  Add a short delay in each
iteration to fix this.
