networking - Will the implementation of RFC3465 Appropriate Byte Count in Linux 2.6.32 be affected by GRO -


the implementation of tcp_abc in linux kernel 2.6.32 like:

323     /* rfc3465: abc 324      * may increase 2 if discovered delayed ack 325      */ 326     if (sysctl_tcp_abc > 1 && tp->bytes_acked >= 2*tp->mss_cache) 327         cnt <<= 1;

if understand correctly, can deal delayed ack, has 2 mss aggregated @ most. when multiple ack packets aggregated lro/gro, implementation works poorly.

so questions is:

  1. will tcp_abc affected lro/gro in linux?
  2. is there way work around?

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
