| Subject: iwlwifi: set default aggregation frame count limit to 31 |
| |
| From: Wey-Yi Guy <wey-yi.w.guy@intel.com> |
| |
| commit 4d80d7210bb5a36a18978d1305b44375ecb857d9 upstream. |
| |
| Multiple MPDUs can be aggregated, transmitted, and finally acknowledged |
| together using a single BA frame. Block ACK (BA) contains |
| bitmap size of 64*16 bits so the maximum frame count is 64. |
| The default value of aggregation frame count suggested by uCode is 31 to |
| achieve best performance. |
