linux-gen: pool: decrease minimum segment size to 2k
Decrease minimum segment size from about 8k to about 2k bytes.
Normal Ethernet frames still fit into first segment, but
SHM reservation size is reduced into about 1/3 what it was.
There is 1GB limit in process mode SHM allocations, so 1/3
reduction makes a big difference there.
