DKconfig73 chipsets. However, in some cases, large bursts may overrun buffers
75 bursts must be disabled and only (slower) small bursts can be used.
84 Also, sometimes larger bursts lead to lower throughput, e.g. on an
86 when going from 8W to 16W bursts.
89 bool "Enable 16W TX bursts (discouraged)"
96 bool "Enable 8W TX bursts (recommended)"
103 bool "Enable 4W TX bursts (optional)"
107 this if you have disabled 8W bursts. Enabling 4W if 8W is also set
111 bool "Enable 2W TX bursts (optional)"
115 this if you have disabled 4W and 8W bursts. Enabling 2W if 4W or 8W
