Subject: net/sfc/base: make max number of TxQ bufs EF10-specific
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=217688651d7085c1f0465838e279d5142423bc3e;p=dpdk.git

net/sfc/base: make max number of TxQ bufs EF10-specific

The define EFX_TXQ_MAX_BUFS is used only by EF10 family implementation.
Since the macro is not used by any drivers, it does not require
exposed libefx interface.
Make the define EF10-specific.
